【Abstract】 Diluted magnetic semiconductors could be used to construct magnetic and electronic device that utilize simultaneously the spin and charge degrees of freedom of carrier. Recent research on ferromagnetic semiconductors has stimulates the development of spintronics. The fabrication of room-temperature ferromagnetic semiconductors, high-efficiency spin injection, and spin manipulation and transport in semiconductors have attracted considerable interest in the past few years. Diluted magnetic semiconductors exhibit strong spin-dependent optical and transport properties, and these effects provide a physical basis for semiconductor spintronics devices.更多还原
