Abstract: X-ray structural analysis reveals that diphthalocyanine-neodymi 
urn, with the composition PcNdPc/sub ox/ (Pc=(C/sub 32/H/sub 16/N/sub 
8/) /sup 2-/, Pc/sub ox/=(C/sub 32/H/sub 16/N/sub 8/) /sup 1-/) exists in 
three polymorphic modifications- tetragonal alpha , orthorhombic gamma , and 
monoclinic beta . Determination of the crystal structure of the beta phase 
(P2/sub 1/ automatic dif f Tactometer , theta -2 theta method, Mo K alpha , 
R=0.052) revealed that it is of the structural type Pc/sub 2/u. The 
sandwich molecules are packed in layers parallel to the ac plane. The 
metal -ligand distance in the structure of Pc/sub 2/M (where M is a metal 
ion) is explained by the ratio between the ionic radii (r/sub Nd/>r/sub 
u/>r/sub Sn/) . The angle of relative rotation of the ligands is apparently 
determined by the character of the packing. Comparing the identity periods 
T/sub perpendicular to / perpendicular to the layers of molecules in the 
alpha , beta , and gamma modifications of diphthalocyanine-neodymium 
(2T/sup alpha //sub (001)/=T/sup beta //sub (001) /sin beta =T/sup gamma 
//sub (101)/), one sees that the M- ligand distances are stable in these 
structures. The relation between the periods T/sup beta //sub (100)/ 
approximately=T/sup beta //sub (010)/ approximately=l/2T/sub (110) //sup 
alpha / in the alpha and beta phases shows that the tetragonal structure is 
evidently layered like the beta phase. (10 Refs)

Abstract: The time to break down distribution of MOS capacitors 
fabricated with a multilayer dielectric was studied. The dielectric was 
composed of 10 nm of thermal silicon dioxide, 15 nm of LPCVD silicon 
nitride, and 1-3 nm of SiO/sub 2/ thermally grown on the Si/sub 3/N/sub 4/ 
layer. The test capacitor was constructed with paralleled storage cells in 
a 64K dynamic memory device. Various electric fields and temperatures were 
used to stress the layered type of capacitors and a control group 
consisting of the same vehicle but having a 3 9 nm silicon dioxide 
dielectric. Stressed units were physically analyzed to isolate the failure 
sites. The type and location of the dielectric breakdown faults were found 
to be similar in both types of dielectric structure. The layered dielectric 
demonstrated superior reliability, however, which is attributed to lower 
detectivity or the spatial variation of the applied electric field within 
the structure. (9 Refs)

Abstract: Optical joint density of states (OJDOS) functions have been 
obtained from Kramers -Kronig analysis of reflectivity measurements for the 
layered-type materials TiS/sub 2/, TiSe/sub 2/, ZrS/sub 2/ , ZrSe/sub 2/, 
HfS/sub 2/ and HfSe/sub 2/. The reflectivity measurements were made at 
near -normal incidence over the photon energy range 0.6-14 ev at 77K. 
Comparison of the OJDOS functions shows that there are many similarities in 
the band shapes which can be explained in terms of the amount of trigonal 
distortion present in the crystal lattice and the differences in binding 
energy of electron levels in the atoms. (9 Refs)

Abstract: The photodecomposition of hydriodic acid on platinized 
n-WSe/sub 2/ single crystals immersed in an aqueous 1 M HI solution was 
studied. During the photodecomposition process, hydrogen evolution only 



occurred on the microscopic defects of the sample surface, whereas iodine 
was produced on the smooth areas where a diffuse orange -red colouring 
appeared. For polycrystalline specimens, however, hydrogen gas bubbles were 
formed over the entire surface, the rate of process being markedly slower 
than on single crystals. The results are discussed with the assumptions 
that the n-WSe/sub 2/ single crystals behave as Schottky- type photochemical 
diodes, that the cathodic reaction takes place on the stepped 
platinum -covered areas and that the anodic reaction occurs on the smooth 
unplatinized areas. (26 Refs)

Abstract: In layered type intercalation electrodes ions are stored 
reversibly during the functioning of secondary batteries. The behaviour of 
the system depends on geometrical and electronic factors. The geometrical 
factors are concerned with the localization of the ions in the host 
structure; they deal with average structure determinations and local 
ordering problems. The diffusion properties of the intercalated ions depend 
on the site geometry, the population of the Van Der Waals gap, the ionicity 
of the bonds in the host, the stoichiometry of the host, and the mechanical 
properties of its slabs. Electrons have to be accommodated by the host. The 
band structure of the host plays an important role in respect of the 
ability to intercalate, the phase limit, and the stability of the products. 
Metal - insulator transition may be induced. Other possible factors such as 
Jahn-Teller effects have also to be considered. (23 Refs)

Abstract: The authors compare the Raman spectra of a-WO/sub 3/ with 
spectra of crystalline WO/sub 3/.H/sub 2/0, WO/sub 3/.2H/sub 2/0 and 
amorphous bulk WO/sub 3/.H/sub 2/0. It is concluded from the results that 
the structure of a-wo/sub 3/ films consists of a layered type structure of 
tungsten hydrates and of a framework structure of tungsten anhydride. The 
band at 590 cm/sup -1/ is attributed to stretching modes of the terminal 



oxygen. By dehydration of amorphous WO/sub 3/. 1.74 H/sub 2/0 one can get 
amorphous bulk samples with a structure similar to the a-wo/sub 3/ thin 
films. (12 Refs)

radiation source at 0.63, 1.15, and 3.39 mu m. The experimentally obtained 
values of n/sub o/ and n/sub e/ are extrapolated from 0 . 6 to 4 . 0 mu m by 
the formulas n/sub o//sup 2/=A+B( lambda /sup 2/+C); n/sub e//sup 2/=K+L/( 
lambda /sup 2/+M) . The values of the extrapolation coefficients A, B, C, K, 
L, and M for CdlnGaS/sub 4/ and TllnS/sub 2/ crystals are obtained using

glottal volume flow and 
by numerical solution of 
in which nonuniform, orthotropic, linear, 
tissue media were surrounded by irregularly 
were either fixed or subject to aerodynamic 



stresses. Spatial nonunif ormity of the tissues was of the layered type, 
including a mucosal layer, a ligamental layer, and muscular layers. 
Orthotropy was required to stabilize the vocal folds longitudinally and to 
accommodate large variations in muscular stress. Incompressibility and 
vertical motions at the glottis played an important role in producing and 
sustaining phonation. A nominal configuration for male fundamental speaking 
pitches was selected, and the regulation of fundamental frequency, 
intensity, average volume flow, and vocal efficiency was investigated in 
terms of variations around this nominal configuration. Vocal intensity and 
efficiency are shown to have local maxima as the conf igurational parameters 
are varied one at a time. It appears that oral acoustic power output and 
vocal efficiency can be maximized by proper adjustments of longitudinal 
tension of nonmuscular (mucosal and ligamental) tissue layers in relation 
to muscular layers. Quantitative verification of the 'body -cover 1 theory is 
therefore suggested, and several further implications with regard to 
control of the human larynx are considered. (17 Refs)

investigated. Magnetization and susceptibility measurements from 4.2 to 
900K and Mossbauer measurements from 4.2 to 300K indicate that all 
compositions of ordered rocksalt (space group R3m) order 
antif erromagnetically at low temperatures. The first-order phase transition 
tracked with all Mossbauer parameters. The Weiss molecular field theory for 
a layered- type antif erromagnet was fitted with two exchange constants. The 
dependence of theta on x was found to be theta - theta /sub a/(l-x)/sup 2/+ 
theta /sub b/2x(l-x)+ theta /sub c/x/sup 2/, where - theta /sub a/=Cr/sup 
3+/-Cr/sup 3+/ interaction, + theta /sub b/-Fe/sup 3+/-cr/sup 3+/ 
interaction and - theta /sub c/=Fe/sup 3+/-Fe/sup 3+/ interaction. A 
spontaneous magnetization associated with iron - substituted crystals 
originated with an epitaxial overgrowth of LiCr/sub 4.75/Fe/sub 0.25/O/sub

Title: A static and dynamic finite element shell - analysis with

Abstract: A system of finite element shell analysis codes, called 
SABOR/DRASTIC, is used to analyse a complex two- layered shell of revolution 
under static and dynamic asymmetric loads. The dynamic analysis is compared 
with experimentally measured response. In this linear elastic analysis, 
emphasis is placed on the inherent flexibility of the finite element method 
in modelling the complex structural geometry of a given test specimen. 
Static studies, which involve variations in important shell parameters, and 
dynamic studies, which provide a successful correlation with experiment, 
are used to illustrate both the detail and the generality with which shell 
analyses may now be performed with confidence.

Abstract: Reviews the different properties of rare -earths and actinides, 
either as pure metals or as in alloys or compounds. Three different cases 
are considered: (i) in the case of 'normal' rare -earths which are 
characterized by a valence of 3, the author discusses essentially the 
magnetic ordering, the coexistence between superconductivity and magnetism 
and the properties of amorphous rare-earth systems; (ii) in the case of 
'anomalous' rare -earths, 1 intermediate -valence 1 systems and ' Kondo 1 systems 
are distinguished. Special emphasis is given to the problems of the 'Kondo 
lattice' (for compounds such as CeAl/sub 2/, CeAl/sub 3/ or CeB/sub 6/) or 
the 'Anderson lattice' (for compounds such as TmSe) . The problem of neutron 
diffraction in these systems is also discussed; and (iii) in the case of 
actinides, the d-f hybridized and almost magnetic metals at the beginning 
of the series are separated from the rare-earth like metals after 
americium. (193 Refs)

Abstract: In order to study the systematics of the Fe-Fe exchange in 
amorphous rare-earth-Fe alloys, without the complications associated with 
the magnetic characteristics of the rare- earth elements, amorphous films of 
Fe alloyed with La, Lu, Y, and zr have been prepared with a wide range of 
Fe concentrations. Magnetization and Mossbauer-ef f ect measurements were 
made. The magnetic properties of the alloys depended critically on the 
choice of rare earth (or rare - earth- like element). YFe and LuFe alloys were 
found to have spin -glass characteristics while LaFe and ZrFe alloys were 
found to be ferromagnetic, but with evidence that exchange fluctuations 
were nearly as large as the average exchange. Thus the nature of the Fe-Fe 
exchange interaction depends critically upon the species of the rare earth. 
The most important parameter in determining the magnetic behavior of these 
alloys appears to be the size of the rare-earth atom, with large rare-earth 
atoms resulting in a smaller ratio of exchange fluctuations to exchange. 
The same dependence of the magnetic properties upon rare-earth size appears 
to be important in the case of magnetic - rare - earth atoms; however, the 
effect of rare-earth-Fe exchange also becomes important and these effects 
are discussed. (30 Refs)

Abstract: The lattice parameters of alloys of f.c.c. beta -La containing 
1.25 to 3.70 at% Am are determined by X-ray analysis. It is found that the 
effective ionic size of the dissolved Am is very close to that of elemental 
Am itself. The unusually weak depression of the superconducting transition 
temperature of beta -La caused by the addition of small amounts of Am is 
discussed- It is suggested that Am ions in La exhibit rare earth- like 
characteristics of trivalency and a localized d-electron configuration. (

Abstract: The lattice parameters of monoclinic europia have been 
determined and contrasted with a range of solid solutions which have the 
same Rare Earth type B structure as europia. These solid solutions were 
based upon samaria and gadolinia which lie on either side of europia in the 
lanthanide series. Curiously, europia does not lie where it would be 
expected to lie on the lattice parameter plots on the basis of its ionic 
radius. This is attributed to its position in the middle of the lanthanide 
series. For the lanthanide oxides with the cubic Rare Earth type C 
structure an anomaly again occurs, but this time for gadolinia. (0 Refs)

characteristics of the alloys are highly reproducible between castings. The 
uniformity of performance within a casting is excellent. The residual 
induction of a typical cerium alloy casting is 5600 G. The coercive force 
is 4800 Oe. The variation of induction with temperature in the region of a 
load line of 2, is 0.08%/ degrees C from room temperature to 100 degrees C.

Abstract: It has been established that Bi/sub 13/V/sub 5/Tio/sub 34/ 
belongs to the ferroelectric family of bismuth-containing compounds with a 
layered compound. The formula unit Bi/sub 2//l/6V5/6Til/60/sub 5/2/3 
corresponds to a layered structure of (Bi/sub 2/O/sub 2/) /sup 
2+/(Bil/6V5/6Til/60/sub 3/2/3) /sup 2-/ with one perovskite- like layer 
between ions of bismuthyl (Bi/sub 2/O/sub 2/) /sup 2+/. The dielectric 
properties indicate that Bi/sub 13/V/sub 5/TiO/sub 34/ has ferroelectric 
properties. The solid-phase process of formation of the compound from a 
mixture of the initial oxides takes place in one stage in the temperature 
range 600-800 degrees C. (8 Refs)

Abstract: The purpose of the present work was to precisely determine 
whether the structures of the complexly substituted phases are centro- or 
noncentrosymmetric and to evaluate some of the ferroelectric and thermal 
characteristics and electrical -conduction properties. The investigations of 
the electrophysical characteristics were carried out on ceramic samples in 
the form of tablets with silver electrodes. The density of the ceramics was 
0.7-0.8 of the x-ray density. The differential thermal analysis in the 
1000-2400 degrees C temperature range was carried out on a system based on 
a high- temperature furnace with a tungsten heating element. The study of 
the nonlinear-optical properties of the phases synthesized was carried out 
by a method involving the generation of the second optical harmonic of 
their laser emission according to the 'reflection' scheme. Samples with a 
grain diameter from 10 to 20 mu were used in this case. (8 Refs)

Abstract: By slow cooling of melts the authors have obtained single 
crystals of the phases Bi/sub 4/GeVO/sub 10.5/ and Bi/sub 8/P/sub 
4-x/Ge/sub 1+x/O/sub 24-x/2/ (x=0.25). They have monitored the chemical 
composition of the crystals, and have investigated them by X-ray 
diffraction, IR spectroscopy, and examination of their dielectric and 
pyroelectric properties. They have obtained new data on the 
crystal lographic characteristics of the phases, and have found that the 
crystals exhibit the pyroelectric effect at room temperature. By 
high- temperature X-ray diffraction, in crystals of the phase Bi/sub 
4/GeVO/sub 10.5/ at 550K they find a first-order phase transition between 
the orthorhombic and tetragonal forms. The crystals of the phase Bi/sub 
4/GeVO/sub 10.5/ are f erroelectrics with a Curie point of 550K. The 
crystals of this phase have a similar structure to crystals of bismuth 
compounds with layered perovskite- like structures. (9 Refs)

Abstract: Single crystals of LMN were synthesized by spontaneous 
crystallization from solution in a melt of lead oxide with added boron 
oxide. By varying the solvent content and the temperature regime over wide 
ranges, it was established that the optimal conditions from growing single 
crystals of LMN are 980-1100 degrees C and 50-60 mass % solvent. The 
resulting single crystals of lead magnesioniobate, when examined under the 
microscope, were seen to be isotropic, with good face development and high 
refractive index n=2.60. (7 Refs)

Abstract: In the study of the sintering kinetics for ceramics based on 
bismuth- containing ferroelectric compounds with a layer perovskite- like 
structure, th liquid phase character of the process has been established 
By modification and addition of the original oxides over stoichiometry, a 
substantial reduction of the sintering temperature and expansion of the 
sintering temperature interval has been achieved for ceramics of 
compositions Bi/sub 3/TiNbO/sub 9/ and Na/sub 0.5/Bi/sub 4.5/Ti/sub 4/O/sub 
15/ . This is explained from the viewpoint of vacancy defect theory. The 
microstructure of bismuth- containing ferroelectric ceramics is formed from 
needle-shaped grains; this is due to preferential crystal growth is 
bismuth- containing compounds along the longer axes of the unit cells in 
these compounds- (8 Refs)

Abstract: In the search for new solid electrolytes, an attempt was made 
at a quantitative allowance for known influences on the mobility. The 
parameter rho /sub ij/=R/sub j/ /sup n/ Sigma /sub 1=1/ /sup 3/ square root 
alpha /sub lj//nR/sub i/ /sup 3/ square root alpha /sub i/ was used, 
representing intermediate positions of type j for a mobile ion of type i. 
An analysis of rho /sub ij/ in the case of halides with a perovskite-like 
structure showed that fluorine anions are much more mobile than cations or 
the other halogen anions. Ranges of existence were found for the fluorides 
promising as solid electrolytes, and such compounds were synthesized and 
investigated. In the elpasolite and cryolite structures, rho /sub ij/ has 
two values corresponding to the two observed types of motion. A comparison 
of the temperatures T/sub ij/ at which motion begins with the calculated 
rho /sub ij/ gave an empirical relation T/sub ij/=T/sub mp/- beta rho /sub 
ij/. No dependence of beta approximately=700 degrees on the kinds of ion 
circumscribing the intermediate position, or on the type of the mobile ion, 
was found for any of the compounds studied. (32 Refs)

Abstract: The reduction of Ca/sub 2/LaFe/sub 3/O/sub 8+z/ in the electron 
microscope shows this solid to decompose into Ca/sub 2/Fe/sub 2/O/sub 5/ 
and LaFeO/sub 3/, two perovskite-related line-phases which, under these 
conditions, appear to be thermodynamically more stable. In kinetic terms, 
the decomposition appears to be of the nucleation and growth type'. 
Microdomains appear to be an essential characteristic of the system since 
they are present in both the reactants and the reaction products. Up to 
nine sets of structurally-related microdomains can simultaneously be 
present within the same crystal. This leads to quite elaborate electron 
diffraction patterns which can be interpreted in terms of perovskite 
superstructures. These results are discussed in terms of diffusion data on 
perovskite- like ferrites. (16 Refs)

Abstract: The family of layered perovskite- like bismuth compounds (LPBC) , 
first discussed by Aurivillius (1949), has the general formula (Bi/sub 
2/O/sub 2/) /sup 2+/ (A/sub n-l/B/sub n/O/sub 3n+l/)/sup 2-/ where A is 
Ca/sup 2+/, Ba/sup 2+/, Pb/sup 2+/ and other ions of the corresponding 
size; B is Ti/sup 4+/, Nb/sup 5+/, Ta/sup 5+/, w/sup 6+/ and other ions 
capable of forming oxygen octahedra; and n=l, 2, 3, . . . represents the 
number of perovskite- like layers between the bismuthyl layers (Bi/sub 
2/O/sub 2/) /sup 2+/. The authors discuss problems arising in the formation 
of new layered bismuth compounds Bi/sub 2/A/sub n-l/B/sub n/O/sub 3n+3/ 
from two others with different numbers of perovski te - like layers n. (11

Abstract: Phase relations were determined in the SrMnO/sub 3-x/-Mn/sub 
3/O/sub 4/ system at elevated temperatures in air using quenching, 
gravimetric, and X-ray diffraction techniques. The system contains one 
intermediate compound, SrMn/sub 3/O/sub 6-x/ (0<or-x<or=0 . 10 between 9 00- 
1200 degrees C) , which decomposes to SrMnO/sub 3-x/ plus Mn/sub 3/O/sub 4/ 
near 1215 degrees C. The existence of an oxygen deficient SrMnO/sub 3-x/ 
having the hexagonal 4 -layer structure was confirmed. Crystals of 
perovskite- like SrMnO/sub 3-x/(x>0.25) were grown from its primary field 
located in the system.

Abstract: In the layer- type f erroelectrics the entrance of the large 
cations A, having noticeably different from Bi/sup 3+/ polarizability and 
sizes, into the octahedral emptiness of the perovskite- like packages 
stipulates changing of the electric field gradient on the nuclei in the 
oxygen octahedra. This effect has been investigated by the Mossbauer 
spectra of Fe/sup 57/ in the layer- type f erroelectrics Bi/sub 2/Bi/sub 
4/Ti/sub 3/Fe/sub 2/O/sub 18/ (A), (PrBi)Bi/sub 4/Ti/sub 3/Fe/sub 2/O/sub 
18/ (B) , Pr/sub 2/Bi/sub 4/Ti/sub 3/Fe/sub 2/O/sub 18/ (C) at temperatures 
between 80 degrees K and 1150 degrees K. For the crystals B and C the weak 
lines of the magnetic splitting conditioned by some second (Magnetoordered) 
phase are observed. According to temperature of disappearance of the 
quadrupole splitting in A, B, and C crystals the Curie temperatures of 
these ferroelectrics 1075 degrees K, 1050 degrees K and 900 degrees K have 
been determined. The Mossbauer measurements show some anomalous variation 
of the isomer shift around the Curie points.

Abstract: A new compound, NaMn/sub 7/O/sub 12/ with the perovskite- like 
arrangement has been synthesized at 80 kbar and 1000 degrees C This 
compound is cubic, a=7.3 03 6 AA space group Im3 with four formula weights 
per unit cell. The structure has been solved by Patterson and Fourier 
synthesis and refined by least -squares based on 142 reflections. The final 
R and wR factors were 0.025 and 0.033, respectively. The A sites of the 
perovskite structure are occupied by sodium and manganese atoms in an 
ordered fashion. The sodium atoms are each surrounded by a 12 -oxygen 
polyhedron whereas the manganese atoms have four nearest oxygens at 1.909 
AA forming a square and four more at 2.688 AA forming a rectangle 
perpendicular to the square. The distortion of the oxygen network from the 
ideal perovskite structure is similar to that found for In (OH) /sub 3/ and 
Sc(OH)/sub 3/. (13 Refs)

Abstract: More than fifty f erroelectrics belong to the Bi/sub 4/Ti/sub 
3/O/sub 12/ family, and all consist of Bi/sub 2/O/sub 2/ layers interleaved 
with perovskite- like M/sub n-l/R/sub n/O/sub 3n+l/ layers. Crystal 
structures of three members of the family have been refined from x-ray and 




neutron diffraction data, elucidating the distortions responsible for 
ferroelectricity. Bi/sub 2/wo/sub 6/(n=l) is orthorhombic, space group 
B2cb; Bi/sub 3/TiNbO/sub 9/ (n=2) orthorhombic, A2/sub 1/am; Bi/sub 
4/Ti/sub 3/0/sub 12/ (n=3) monoclinic, Pc, but very nearly orthorhombic, 
B2cb. Similar distortions occur in all three structures, with large 
rotational motions accompanying the polarization along a. Below the 
transition, a strong Bi-0 bond is formed to the apex oxygen of the 
perovskite layer, tilting the octahedra and producing antiparallel shifts 
along b. Symmetry differences in the even- and odd- layered compounds can be 
explained by the type of strains produced in the perovskite layer. The 
octahedral cations (w, Ti, Nb) are the major contributors to the 
spontaneous polarization, moving about 0.4 AA toward an octahedral edge (

Abstract: The structures of NdAlO/sub 3/ and SmAlO/sub 3/ have been 
refined with precision from single crystal x-ray data. Both compounds have 
the perovskite -like arrangement. In the trigonal NdAlO/sub 3/ (space group 
R3c) the neodymium atoms have coordination number 12, the average Nd-0 
distance being 2.660 AA. The aluminum atoms are surrounded by a trigonally 
distorted octahedron, with an average Al-0 distance of 1.896 AA. In the 
orthorhombic SmAlO/sub 3/, the samarium atoms are surrounded by 12 -oxygen 
polyhedra but the coordination is slightly less than 12. The average Sm-0 
distance is 2.658 AA. The results incidate that with the orthorhombic to 
trigonal transition, the distortion of the rare earth polyhedron decreases, 
whereas that of the aluminium octahedron increases slightly. The overall 
distortion of the structure decreases. A comparison of the SmAlO/sub 3/ 
structure with that of its iron counterpart shows that the distortion from 
the ideal cubic perovskite structure is quite different. Therefore, the two 
compounds cannot be considered truly isostructural . (17 Refs)

Abstract: The crystal structure of LaFeO/sub 3/ has been refined from

index of 0.035. LaFeO/sub 3/ has the orthorhombic perovskite- like 
structure, though the rare earth polyhedron is quite distorted relative to 
the ideal cubic arrangement. The results indicate that in contrast to the 
other members of the orthoferrite series the coordination number of the 
lanthanum atoms is no longer 8. The Fe octahedron is only slightly 
distorted and the average Fe-0 and 0-0 distances are 2.006 AA and 2.837 aa,

Abstract: Phase stability relations among four hexagonal perovskite- like 
structures as well as the cubic perovskite structure have been studied for 
several oxides (BaMnO/sub 3/ and SrMnO/sub 3/) and fluorides (CsMnF/sub 3/, 
RbNiF/sub 3/ and TINiF/sub 3/) at high pressure. A series of high pressure 
transformations are found to occur in the order of the packing sequence 
along the hexagonal c axis (or cubic 111 axis) of (ab) , (ababcbcac) , 
(abac) , (abcacb) and (abc) with increasing pressure. This order is 
corresponding with the increasing order of the proportion of the cubic 
close-packed layers in the hexagonal close-packed structure. It is 
suggested that the tolerance factor of the perovskite structure and the 
Coulomb repulsive force play an important role in determining the crystal 
structure and its order in the series of phase transformations at high 
pressure.

Abstract: Many ABO/sub 3/ perovskite- type compounds exhibit an 
orthorhombic symmetry with a approximate ly=b and c approximate ly=a square 
root 2 axis length. An important exception is the compound SrCeO/sub 3/ 
which exhibits a strongly distorted perovskite- type structure with 2 a 
approximately=b- However, the doubling of the b axis in SrCeO/sub 3/ 
disappears both in the SrCeO/sub 3/-SrZrO/sub 3/ and in the SrCeO/sub 
3/-BaZrO/sub 3/ solid solutions in all the compositions differing from the 
stoichiometric SrCeO/sub 3/. (8 Refs)

Abstract: Electrically conductive oxide electrodes were investigated, and 
the piezoelectric characteristics were measured for lead zirconate titanate 
(PZT) resonator with the conductive oxide electrodes. Printable pastes were 
made using conductive oxides having perovskite type structure, such as 
BaPbO/sub 3/, BaPb/sub 1.2/O/sub 3/, BaPb/sub 0.8/Bi/sub 0.2/O/sub 3/„ 
BaPb/sub 0.8/Sb/sub 0.2/O/sub 3/ and La/sub 0.5/Sr/sub 0.5/CoO/sub 3/, with 
glass frits and organic vehicles, the electrical resistivities of these 
pastes were measured at room temperature by four probe method, which were 
1.4*10/sup -2/ ohm-cm for BaPbO/sub 3/ paste and 2.3*10/sup -2/ ohm-cm for 
La/sub 0.5/Sr/sub 0.5/CoO/sub 3/ paste. The piezoelectric resonators were 
obtained with Kp=39%, tan delta =3.2% and C=24nF for an electrode of 
BaPbO/sub 3/ paste and with Kp=31%, tan delta =6.8% and C=39nF for an 
electrode of La/sub 0.5/Sr/sub 0.5/CoO/sub 3/ paste. (8 Refs)

Abstract: Highly sensitive optical detectors have been fabricated by 
using perovskite type superconductor BaPb/sub 0.7/Bi/sub 0.3/O/sub 3/ (BPB) 
thin films. Optical signals create quasi -particles and induce changes in 
the superconducting order parameter. These changes are measured by 
tunneling junctions along grain boundaries in the BPB polycrystalline thin 
films. The sensitivity is about 10/sup 3/ V/W in the 1.0 approximately 10 
mu m wavelength range and they can respond up to 600 MHz at the wavelength 
of 3.2 mu m. The observed results suggest that the BPB detectors are 
suitable for application in optical communication systems and infrared 
spectrometers. (7 Refs)

Abstract: The paramagnetic resonance spectrum of Fe/sup 3+/ in lead and 
strontium titanates has been studied at Q band and 70GHz, and at 
temperatures down to 4.2 degrees k. The zero- field splittings have been 
measured directly giving values of 1 . 06+or- 0 . 05cm/sup -1/ for lead titanate 
at room temperature and 2 . 698+or- 0 . 006 cm/sup -1/ for strontium titanate. 
The spectrum for lead titanate can be fitted to a spin Hamiltonian with 
g/sub mod mod /-g/sub i/=2.0, D=0.53 cm/sup -1/ and a=2 . 70+10/sup -2/cm/sup 
-1/ and a 20% increase in the zero- field splitting parameter is observed on 
cooling from room temperature to 77 degrees K indicating a small lattice 
deformation. A second transition tentatively identified as arising from a 
charge -compensated site having a zero- field splitting equal to 1.8+or-0.1 
cm/sup -1/, has also been observed. The spectrum for strontium titanate has 
been studied at 35GHz and 70GHz and it is found that the Hamiltonian 
parameters differ slightly from those previously determined from the 10 GHz 
spectrum. (11 Refs)

Abstract: Reducing high-purity BaTiO/sub 3/ in hydrogen for 1 h at 1275 
degrees C leads to an oxygen deficiency x- 0.003 6 in BaTiO/sub 3-x/ with 
maintenance of the tetragonal/cubic perovskite- type structure. Reduction at 
1325 degrees C leads to x = 0.0073 and brings about transformation to the 
hexagonal modification. Up to 1500 degrees C (x - 0.0233) no further phase 
change occurs. Annealing the oxygen -deficient hexagonal phase in oxygen at 
850 degrees C for 2 h produces stoichiometric samples which are still 
hexagonal, whereas the tetragonal/cubic structure is restored by heating 
for 1 h at 1350 degrees C. (16 Refs)

Abstract: Calculations are made of the maximum relative displacement and 
of the force acting on the anion in rare -earth aluminates for rhombohedral 
and tetragonal lattice distortion. The results are plotted against the 
radius of the lanthanide ion; the curves are discussed, and it is concluded 
that rare -earth aluminates with the perovskite structure and rhombohedral 
lattice distortion can exist between ionic radii of 0.942 and 0.91 AA.

Abstract: Correction of Lorentz field coefficients in a Perovskite- type 
crystal is discussed by considering orthorhombic deformation of a simple 
cubic lattice. If one considers the deformation of crystal structure from 
the simple cubic lattice to the orthorhombic lattice a change of the 
internal field at some respective points caused by the dipole interaction 
is calculated. By applying the results, quantitative discussions are 
possible for many phenomena accompanied by the lattice deformation namely, 
f erroelectricity, piezoelectricity, photoelastici ty and so on. As an 
example calculations are made to estimate the birefringences of the 
BaTiO/sub 3/ and wo/sub 3/ crystals.
