Symmetry breaking of the surface mediated quantum Hall Effect in Bi2Se3 nanoplates using Fe3O4 substrates

Bottom surface-induced ferromagnetism in Bi2Se3 nanoplate devices on SiO2 and ferromagnetic insulator substrates decouples quantum Hall effects, revealing shifted half-integer QHEs in a three-channel model.
