| Abstract: | 6% 57Fe doped titanium oxide films, prepared by pulsed laser deposition (PLD) on sapphire substrate at 650°C under various vacuum conditions, were characterized mainly by conversion electron Mössbauer spectrometry (CEMS). Two magnetic sextets with hyperfine fields 33 and 29 T, and one doublet were observed in the CEMS spectra of TiO2 films prepared under PO2 = 10?6 and 10?8 torr, which showed ferromagnetism at room temperature, whereas only the doublet of paramagnetic Fe3+ species was observed for the film prepared under PO2 = 10?1 torr. |
