Extended Data Fig. 5: Hall resistance.
a,b, Longitudinal resistance R (a) and Hall resistance Rxy (b) as a function of B and ν at T = 50 mK and E = 0 mV/nm. Large bias (above the critical current) is applied, and superconductivity is not observed. The strong Rxy response below filling 0.9 under small magnetic fields is an artifact because of the large magneto resistance and the coarse field step. The vHS manifests a peak in R (a) and a sign change in Rxy (b). The dashed lines are a guide to the eye of the location of the vHS for negative magnetic fields. The vHS is located at ν < 1 for B = 0 and rapidly disperses with B likely due to the combined Zeeman and orbital effects. c,d, Linecut of a,b at ν = 0.8 (c) and ν = 1.1 (d) with fine field scans. The measurement configuration is shown in the inset. We symmetrize and anti-symmetrize the response under positive and negative fields to obtain R and Rxy, respectively. Both forward and backward field scans are displayed. Magnetic hysteresis is not observed. Anomalous Hall effect is also not observed (Rxy = 0). The artifact in b is removed under fine field scans.
