Superconductivity in Bi based Bi2PdPt

Abstract

We report the synthesis and properties of superconducting Bi₂PdPt, a new member of the Bi–Pd based compounds that are known for simultaneous existence of topological surface states and superconductivity. It crystallizes in a hexagonal structure having space group P6₃/mmc. A detailed investigation of the properties via transport, magnetization and specific heat measurements confirms bulk superconductivity with a transition temperature, T_C, of 4.0 (1) K in the moderate coupling limit.
