摘要：

Magnetic and electronic properties of Fe-doped anatase TiO2-delta thin films grown by a sol-gel method have been investigated by vibrating-sample magnetometry (VSM), conversion electron Mossbauer spectroscopy ( CEMS), and Hall effect measurements. VSM measurements revealed that the anatase Ti1-xFexO2-delta films exhibit ferromagnetic behavior at room temperature for a certain range of x. CEMS spectra revealed that Fe2+ and Fe3+ ions coexist, substituting the octahedral Ti4+ sites. By appropriate Fe doping, the Ti1-xFexO2-delta films exhibited p-type character but the observed room-temperature ferromagnetism turned out to be independent of the hole concentration.
