Extended Data Fig. 5: Magnetic hysteresis at 0.3 K and 2 K at different doping.

a, Color plots of four-probe resistance Rxy as a function of carrier density n and displacement field E for the small hole doping VPHM region at B = 0.5 T and T = 0.3 K. b & c, Rxy as the magnetic field B is scanned, showing clear hysteresis loops within the droplet region. Curves correspond to dots with the same color in a at E = 5 mV/nm and different ne at T = 0.3 K a and 2 K b, and are shifted vertically for clarity. Solid and dashed curves correspond to forward and backward scanning of the B field. At 2 K, the coercive field of magnetic hysteresis almost vanishes, consistent with the disappearance of the ferro-valleytronic order at 2 K.
