Spintronics, at the cross of magnetism, electronics and informatics, is a new emerging field of research in considerable expansion. The advantages of the spintronic devices would be nonvolatility , increased data processing speed, decreased electric power consumption and increased integration densities compared with conventional semiconductor electronic devices. In this paper, an introduction to semiconductor spintronies that includes magnetic semiconductor, spin injection into semiconductor, spin detection and spin transport, etc, is given. Thereafter, the current development of the investigation on semiconductor spintronics and its applications in the electron spin devices and realization of quantum computers are reported in this paper.
