Fig. 5: First and second harmonic Hall measurements for extraction of BDL and BFL.
a First harmonic Hall voltage \({V}_{xy}^{\omega }\) as a function of in-plane angle γ (inset, an optical image of the patterned Hall bar). The solid black line is a fit to Eq. (1). b Second harmonic Hall voltage \({V}_{xy}^{2\omega }\) as a function of γ. The solid black line is a fit to Eq. (2), and the solid red and blue lines denote the field-like and damping-like + Nernst effects (ordinary and anomalous) contributions respectively. c, d The field-like and damping-like + ANE contributions to \({V}_{xy}^{2\omega }\) as a function of 1/Bext and 1/Beff respectively as described in the main text. The red lines are linear fits. Measurements were performed with an AC current of 1 mA amplitude.
