Superconductivity at 600 mK in a novel ternary platinum phosphide $\mathbf{SrPt_6P_2}$

ORAL

Abstract

In the course of our search for new superconducting materials, we have synthesized a novel, metal-rich ternary platinum phosphide superconductor with a unique structure type and an onset $\mathrm{T_c}$ of 600 mK, $\mathrm{SrPt_6P_2}$. The crystal structure was determined by single crystal X-ray diffraction, and features a unique three-dimensional anionic network of vertex-shared $\mathrm{Pt_6P}$ trigonal prisms. Furthermore, we have investigated the superconductivity in this material resistively, magnetically, and calorimetrically. The results of these studies will be presented and discussed.
