“…Diluted magnetic semiconductors (DMSs) based on III-V compound semiconductor crystals doped with 3d impurities of the transition metal group attract considerable interest with the prospects of the development of new spintronic devices combining useful properties of semiconductors and ferromagnets (Jungwirth et al, 2006). Since the discovery of carrier-induced ferromagnetism in Mn-doped InAs and GaAs (Munekata et al, 1989;Ohno et al, 1996) much effort has been devoted to the study of Mn doping of III-V compound semiconductors including GaN ( Shon et al, 2002), GaSb (Matsukura et al, 2000), InP (Park and Kang, 2007) and GaP (Overberg et al, 2001). At the same time the iron doped semiconductors were less studied.…”
