a,b, Magnetic-field dependence of \({R}_{{xy}}\) and \({R}_{{xx}}\) from device 2 and 3 at 1.6 K. Quantized Hall resistance at zero magnetic field is observed in device 2; \({R}_{{xx}}\) is not measured. The resistance quantization in device 3 is nearly perfect at a small magnetic field, accompanied by a significant drop in \({R}_{xx}\). c,d, The same as a,b for device 1 measured from different pairs of probes (than the result shown in the main text) at 300 mK. The labeling of the electrodes is shown in Extended Data Fig. 1. Nearly quantized resistance with similar magnetic-field dependence is observed. The coercive field varies slightly from device to device.
