a Rw versus Bz at different currents. b Bz-dependent R2w at various currents. Typical pairs of antisymmetric peaks (R2w) are marked by dashed lines in matching colors. R2w at 500 nA (black line) shows a similar behavior to ΔIc (orange line). The green dashed line indicates the regions near the critical fields, while the other dashed line marks the areas near the oscillating peaks or valleys. c Typical \(\left\vert {R}_{2w}\right\vert\) as a function of current at 20 mK for different oscillating peaks. The average \(\left\vert {R}_{2w}\right\vert\) values are obtained using pairs of antisymmetric peaks near the dashed lines in (b). The error bars primarily originate from discrepancies between average \(\left\vert {R}_{2w}\right\vert\) and the observed values. d Antisymmetric R2w and ΔIc as a function of Bz in device S1. The R2w is measured at Iac = 70 nA.
