Abstract
⺠We have synthesized single phase Mn doped TiO2 thin films using PLD technique. ⺠XRD results indicate that films exhibit single phase nature with rutile structure and exclude the secondary phase. ⺠Field cooled magnetization and magnetic hysteresis loop studies infer that Mn doped TiO2 films show room temperature ferromagnetism. ⺠XMCD measurements at Mn L3,2 edge show that Mn2+ ions contribute to the ferromagnetism. ⺠NEXAFS spectra measured at Mn and Ti L3,2 edge show that Mn exist in +2 valence state, whereas, Ti is in +4 state in Mn doped TiO2 films.
