a Longitudinal electrical resistivity ρxx (blue, left axis) and Hall resistivity ρxy (red, right axis) and as a function of B at T = 50 mK with B applied in z for 0 T ≤ B ≤ 3 T (upper panel) and 0 T ≤ B ≤ 9 T (lower panel). The blue arrows mark the onset of a Landau level. The blue numbers label the index N of the Landau level and the red numbers label the corresponding value of σxy with respect to (e2/h)kF,z/π. b Variation of the longitudinal electrical resistivity Δρxx as a function of B (upper panel, left axis), γ B·dρxy/dB (right axis, upper panel) (γ = 0.04) and Landau-index fan diagram (lower panel) as a function of B−1 at T = 50 mK with B applied in z. c ρxx and d ρxy as a function of B for various temperatures 4 K ≥ T ≥ 50 mK with B applied in z.
