We try to synthesize the Co doped TiO2 dilute magnetic semiconductor structure via thermal treatments under vacuum environment, and study its magnetic property. The results reveal that during thermal treatments in a vacuum environment, the Co grains may form the oxide phase structure, and lose their magnetic properties.

研究结果发现在真空高温退火过程中，虽然钴粒子会均匀扩散至非晶的二氧化钛薄膜，其铁磁性的行为却因此消失，由实验结果推断在高温回火过程中，钴可能形成反铁磁的氧化物的结构。
