Quantum Linear Magnetoresistance: A Modern Perspective

Abstract

Magnetoresistance is a powerful probe for characterizing the intrinsic physics embedded in materials. Among its various manifestations, linear magnetoresistance has a long history and continues attracting research interest. In contemporary studies, a clear understanding of the magnetoresistance character of quantum origin is more crucial than ever for the study of emerging materials. In this perspective, we examine the linear magnetoresistance of quantum mechanism, from its theoretical basis to experimental studies, and discuss open questions and promising future research directions in this field.
