Rxx(Vb/db, Vt/dt) at B = 13.6 T for the forward (a) and backward (b) sweeps, respectively, zoomed in from Supplementary Fig. S26. The pink-shaded regions indicate the SdH oscillations arising from MLG, while the fringes without shading denote the SdH oscillations originating from TLG. The red and gray bars represent the polarized (P) and nonpolarized (N) phases. Rxx (c) and Gxy (d) at Vt/dt = 270 mV nm−1 for the forward (red) and backward (blue) scans, respectively. Pf (Nf) and Pb (Nb) are the polarized (nonpolarized) phases for forward and backward sweeps. Rxx (e) and Gxy (f) at Vb/db = −45 mV nm−1 for the forward (purple) and backward (gray) scans.
