Superconductivity, magnetic order and intermediate valence in the new platinum germanium skutterudites MPt4Ge12 (M=Sr,Ba,La,Ce,Nd,Pr,Eu)

  • 1. Max-Planck-Institut fuer Chemische Physik fester Stoffe, Dresden (Germany)

Description

In the new germanium-platinum compounds with the filled-skutterudite crystal structure MPt4Ge12 superconductivity was observed for the non-magnetic cations M=Sr2+, Ba2+, La3+ and for Pr3+ which has a singlet crystal field ground state. The isostructural compound with cerium shows no superconductivity above 0.45 K but displays intermediate valence. With the cations Nd3+ and Eu2+ magnetic order is found at temperatures below 1.8 K. Interestingly, from Curie-Weiss fits to magnetic susceptibility data much stronger antiferromagnetic interactions could be inferred
