- We propose a mechanism for insulating ferromagnetism in the honeycomb Hubbard model of semiconductor moiré superlattices. The ferromagnetism emerges at critical charge transfer regime, stabilizing the quantum anomalous Hall state without Hund's coupling. We further note the ferromagnetic exchange applies to general charge transfer systems when breaking particle-hole symmetry.
