Superconductivity in Bi based Bi2PdPt

Abstract

We report synthesis and properties of superconducting Bi${}_2$PdPt, a new member of Bi-Pd based compounds known for their simultaneous existence of topological surfaces states and superconductivity. It crystallizes in a hexagonal structure having space group $P{6}_3/mmc$. A detailed investigation of the properties via transport, magnetization, and specific heat measurements confirm bulk superconductivity with transition temperature, \textit{T}${}_C$ = 4.0(1) K in moderate coupling limit.
