  bibo_abstract:
  - Electrons in moiré flat band systems can spontaneously break time-reversal symmetry,
    giving rise to a quantized anomalous Hall effect. In this study, we use a superconducting
    quantum interference device to image stray magnetic fields in twisted bilayer
    graphene aligned to hexagonal boron nitride. We find a magnetization of several
    Bohr magnetons per charge carrier, demonstrating that the magnetism is primarily
    orbital in nature. Our measurements reveal a large change in the magnetization
    as the chemical potential is swept across the quantum anomalous Hall gap, consistent
    with the expected contribution of chiral edge states to the magnetization of an
    orbital Chern insulator. Mapping the spatial evolution of field-driven magnetic
    reversal, we find a series of reproducible micrometer-scale domains pinned to
    structural disorder.@eng
