Quasilinear quantum magnetoresistance in pressure-induced nonsymmorphic superconductor chromium arsenide

Abstract

The electronic structure of the helimagnet CrAs is unusual due to its nonsymmorphic crystal symmetry. Here, the authors observe quasilinear magnetoresistance close to a pressure-driven superconducting transition, which may arise from the interaction of the band structure and magnetic fluctuations.
