Effect of disorder on high-spin topological superconductor YPtBi

ORAL

Abstract

YPtBi has been a candidate to study the interplay between superconductivity and topological band structure. With a non-centrosymmetric half-heusler structure it has a topological band structure and an extremely low carrier density. Along with that it also hosts a superconducting transition at 0.8K with a high spin (j=3/2) pairing state and a nodal order parameter. In order to gain some further insight into the nature of the superconducting state, we report on a variety of measurements to understand the effect of disorder on the material and probe the pair breaking effect as a function of disorder on the superconducting state.
