Ferromagnetic III-V semiconductors, such as (Ga,Mn)As and (In,Mn)As, are among the promising materials in the field of semiconductor spintronics because of their good compatibility with the high quality III-V heterostructures. We show several examples of the novel spin-related properties of heterostructures containing a ferromagnetic component: (1) all-semiconductor (Ga,Mn)As/(Al,Ga)As/(Ga,Mn)As trilayers exhibiting spin-dependent scattering and tunneling magnetoresistance; (2) resonant tunneling structures with (Ga,Mn)As emitter, where spontaneous spin-splitting of the valence band is probed; (3) spin-light emitting diodes, in which spin-injection can be observed and (4) field effect transistor structures with a (In,Mn)As channel layer, making it possible to control the ferromagnetism by an electric field.
