Extended Data Fig. 3: Zero-bias MCD images at varying fillings and electric fields.

a, b, Zero-bias spontaneous MCD images at varying filling factors and fixed \(E=0.628\) V/nm (a) and at varying electric fields and fixed \(\nu =1\) (b). Temperature is at 1.6 K. Black dashed lines mark the sample boundaries. Strongest MCD is observed at the Chern insulating state (\(\nu =1\) and \(E=0.633\) V/nm); the MCD signal decreases with detuned \(\nu\) and \(E\). MCD inhomogeneity originating from strain and/or twist angle disorders is also observed.
