Abstract

The nature of non-saturating magnetoresistance (MR) in topological materials is an important issue in condensed matter research but remains elusive. The authors here report the nonlinear MR at room temperature in WTe2 with temperature-driven inversion due to the temperature-induced changes in Fermi surface convexity.
