a, Dependence of ρyx(0) (blue squares) and ρxx(0) (red circles) on T. All measurements were taken at μ0H = 0 T after magnetic training. b, c, Dependence of ρyx (b) and ρxx (c) on μ0H, measured at different temperatures and Vg = Vg,0. d–g, Dependence of ρyx (d, e) and ρxx (f, g) on μ0H, measured at different gate voltages (d, f, Vg < Vg,0; e, g, Vg ≥ Vg,0) and T = 25 mK. When Vg is tuned away from Vg,0, ρyx and ρxx show additional transition features once the external magnetic field changes the polarity. We speculate that these features are probably a result of the heating generated in the dilution fridge and/or the indium contacts used in our samples.
