Extended Data Fig. 2: Current dependence of the linear and nonlinear magnetoresistances.
From: Probing the quantum metric of 3D topological insulators

a, Linear magnetoresistance measured at 10 K at increasing current with the field applied in the sample plane and perpendicular to the current direction. b, Nonlinear magnetoresistance measured simultaneously to the linear magnetoresistance in a. c Two-probe linear I-V curve demonstrating ohmic contacts.
