Heavy-fermion superconductivity in Ce2PdIn8

Abstract

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 clean-limit superconductivity sets in at Tc = 0.7 K at ambient pressure, likely at a verge of a quantum phase transition that manifests itself in a form of distinct non-Fermi liquid features in the bulk normal state characteristics.
