- Abstract
Combining expts. and ab initio models we report on SrPt4Ge12 and BaPt4Ge12 as members of a novel class of superconducting skutterudites, where Sr or Ba atoms stabilize a framework entirely formed by Ge-atoms. Below Tc = 5.35 K, and 5.10 K for BaPt4Ge12 and SrPt4Ge12, resp., electron-phonon coupled supercond. emerges, ascribed to intrinsic features of the Pt-Ge framework, where Ge-p states dominate the electronic structure at the Fermi energy.
