a Schematic drawing of the measurement setup. b Temperature-dependent of the first-harmonic longitudinal resistance at different out-of-plane B-fields with excited a.c. current of 0.6 mA. c Temperature dependence of the \({V}_{{xx}}^{3\omega }\) (upper panel) and \({V}_{{xy}}^{3\omega }\) (lower panel) at different out-of-plane B-fields with excited a.c. current of 0.6 mA. Inset in lower panel shows the zoom-in view of \({V}_{{xy}}^{3\omega }\) at low temperatures.
