摘要

Diluted magnetic semiconductors (DMSs) represent a syner-getic collaboration between charge-based semiconductors and spin-based magnetism. Equipped with good structural, chemical, and electrical compatibilities with conventional semiconductors, DMSs are emerging as promising spin injection sources; a prerequisite for advancing spintronics. Following the success of (Ga, Mn)As, the discovery of many DMS materials with room-temperature ferromagnetism (RTFM) has generated a lot of interest because of both scientific and technological importance. Especially, theoretical studies predicted and experiments verified that some wide-band-gap oxide semiconductors, such as ZnO and TiO_2, doped with transitional metals, are DMSs. However, it is a general consensus that the experimental results on oxide-based DMSs are difficult to interpret owing to the low doping concentration and the poor conductivity, both disfavoring the carrier-based mechanisms. Furthermore, many experimental results were plagued by the precipitates of doped magnetic elements and even unintentional contaminations during sample handling.
