APPEARANCE OF ROOM-TEMPERATURE FERROMAGNETISM IN CU-DOPED TIO2-DELTA FILMS

In recent years there has been an intense search for room temperature ferromagnetism in doped dilute semiconductors, which have many potentially applications in spintronics and optoelectronics. We report here the unexpected observation of significant room temperature ferromagnetism in a semiconductor doped with nonmagnetic impurities, Cu-doped TiO
