Abstract :
Summary form only given. We discuss materials options to build spintronic devices illustrated by our recent experimental findings in fabricating NiMnSb epitaxial magnetic contacts, ferromagnetic/insulator/semiconductor (FM/I/S) spin-LED´s and (Al,Ga)MnAs-based heterostructures. We use all the bandgap engineering tricks of advanced semiconductor devices to exploit and enhance spin-dependent effects.
