| Abstract | Abstract Room-temperature ferromagnetic properties of Mn-doped reduced titanium dioxide ( Ti 1 - x Mn x O 2 - δ ) thin films with rutile structure synthesized by a sol–gel method have been detected for a limited range of Mn composition ( x ) . The Ti 1 - x Mn x O 2 - δ films were found to be p-type semiconducting with hole concentration near 10 19 cm - 3 . The observed ferromagnetism in the Ti 1 - x Mn x O 2 - δ films is not related to the hole concentration but related to x . The room-temperature ferromagnetism is attributable to magnetic polaron formed by trapped electron in oxygen vacancy and magnetic ions around it. Thus, the existence of oxygen vacancies is necessary for the room-temperature ferromagnetism. |
