Dilute ferromagnetic semiconductors: Physics and spintronic structures

This review compiles results of experimental and theoretical studies on thin films and quantum structures of semiconductors with randomly distributed Mn ions, which exhibit spintronic functionalities associated with collective ferromagnetic spin ordering. Properties of $p$-type Mn-containing III-V as well as II-VI, IV-VI, ${V}_{2}\text{\ensuremath{-}}{\mathrm{VI}}_{3}$, I-II-V, and elemental group IV semiconductors are described, paying particular attention to the most thoroughly investigated system (Ga,Mn)As that supports the hole-mediated ferromagnetic order up to 190 K for the net concentration of Mn spins below 10%. Multilayer structures showing efficient spin injection and spin-related magnetotransport…
