Quantum oscillations and superconductivity in YPtBi under pressure

The half-Heusler RPtBi series is home to a variety of magnetic and superconducting compounds. The nonmagnetic members are especially interesting as they are thought to host topologically non-trivial band structures. The semimetal YPtBi has gathered much interest as an exciting platform for unconventional superconductivity, potentially with exotic j = 3/2 pairing states. An important tool for studying unconventional superconductivity in these systems is the application of hydrostatic pressure. While YPtBi has been studied extensively since its discovery as a superconductor, its behavior under pressure has remained relatively underexplored, with little done to investigate its electronic structure under pressure. Here, we present magnetotransport data taken on high-purity, semimetallic YPtBi under pressure, and discuss the effects of pressure on the resistivity, quantum oscillations, and superconducting transition in YPtBi.
