We report low-temperature specific heat measurements in magnetic fields up to 12 T applied parallel and perpendicular to the tetragonal c-axis of the heavy fermion superconductor Ce$_2$PdIn$_8$. In contrast to its quasi-two-dimensional (2D) relative CeCoIn$_5$, the system displays an almost isotropic upper critical field. While there is no indication for a FFLO phase in Ce$_2$PdIn$_8$, the data suggest a smeared weak first-order superconducting transition close to $H_{c2}\approx 2$ T. The...

When a second-order magnetic phase transition is tuned to zero temperature by a non-thermal parameter, quantum fluctuations are critically enhanced, often leading to the emergence of unconventional superconductivity. In these `quantum critical' superconductors it has been widely reported that the normal-state properties above the superconducting transition temperature $T_c$ often exhibit anomalous non-Fermi liquid behaviors and enhanced electron correlations. However, the effect of these strong...

The compound Ce2PdIn8 is a recently discovered novel member of the series Ce(n)TIn(3n+2), where T = d-electron transition metal, and n = 1 or 2. So far, only the phases with T = Co, Rh and Ir have been intensively studied for their unconventional superconducting behaviors at low temperatures. By means of magnetic susceptibility, electrical resistivity and heat capacity measurements we provide evidence that also Ce2PdIn8 has a superconducting ground state with strong heavy-fermion character. The...

Single crystals of Ce2PdIn8 were studied by means of magnetic susceptibility, electrical resistivity and specific heat measurements. The compound was found to be a heavy fermion clean-limit superconductor with Tc = 0.68 K. Most remarkably, the superconductivity in this system emerges out of the antiferromagnetic state that sets in at TN = 10 K, and both cooperative phenomena coexist in a bulk at ambient pressure conditions.
