ABSTRACT
Room-temperature ferromagnetic oxide semiconductor Co-doped TiO2 films are grown on glass substrates by sputtering method. Conducting films are ferromagnetic at room temperature that is consistent with the carrier-mediated nature of the ferromagnetism. Nearly full-polarized magnetization, large magneto-optical effect, and anomalous Hall effect are observed at room temperature. The magneto-optical effect shows nearly fourfold enhancement in a one-dimensional magnetophotonic crystal structure with a standard dielectric multilayer (SiO2/TiO2).
