Abstract
III–V ferromagnetic semiconductors allow epitaxial integration of ferromagnetism with nonmagnetic semiconductor heterostructures and offer opportunities to explore properties that combine conventional semiconductor physics with magnetic cooperative phenomena. Here, we review spin-dependent phenomena observed in III–V-based ferromagnetic semiconductor heterostructures, which include spin-dependent scattering, tunnel magnetoresistance, resonant tunneling with ferromagnetic emitter, spin injection, and electric field control of ferromagnetism.
