a, Magnetic-field dependence of \({R}_{{xx}}\) and \({R}_{{xy}}\) at 1.6 K for the Chern insulating state (\({V}_{{tg}}\) = -4.693 V, \({V}_{{bg}}\) = 3.528 V). Nearly quantized \({R}_{{xy}}\) and vanishing \({R}_{{xx}}\) are observed at magnetic fields higher than 0.2 T. b, The corresponding magnetic-field dependent MCD. A hysteresis is observed, consistent with the transport results and with the emergence of a ferromagnetic state.
