Abstract
Diluted magnetic semiconductors (DMSs) have attracted considerable attention because they are believed to be ideal candidate materials used for the high-density, high-speed and low-power electronic devices [1]. Ferromagnetic DMSs with Curie temperature above room temperature is usually obtained by doping magnetic ions as impurities into the host semiconductors. It has been theoretically predicted that magnetic ions doped ZnO DMSs would have ferromagnetic property with a Curie temperature higher than the room temperature [2]. As a magnetic ion, Cr <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> is also used as a doping element into ZnO semiconductor because of the closer ionic radius to Zn <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2+</sup> and the relative ferromagnetic stability of Cr-doped ZnO DMSs.
