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.
