The nature of Fermi surface defines the physical properties of conductors andmany physical phenomena can be traced to its shape. Although the recentdiscovery of a current-dependent nonlinear magnetoresistance in spin-polarizednon-magnetic materials has attracted considerable attention in spintronics,correlations between this phenomenon and the underlying fermiology remainunexplored. Here, we report the observation of nonlinear magnetoresistance atroom temperature in a semimetal WTe2, with an interesting temperature-driveninversion. Theoretical calculations reproduce the nonlinear transportmeasurements and allow us to attribute the inversion to temperature-inducedchanges in Fermi surface convexity. We also report a large anisotropy ofnonlinear magnetoresistance in WTe2, due to its low symmetry of Fermi surfaces.The good agreement between experiments and theoretical modeling reveals thecritical role of Fermi surface topology and convexity on the nonlinearmagneto-response. These results lay a new path to explore ramifications ofdistinct fermiology for nonlinear transport in condensed-matter.
