Oxygen vacancy enhanced the room temperature ferromagnetism in Ni-doped TiO2 thin films
Physics Letters A 364 (2007) 318-322，-0001，（）：
Ni-doped TiO2 anatase thin films were fabricated by reactive magnetron sputtering on SiO2 substrates. The doping and annealing effects on structure and magnetism for the films have been systematically investigated. The results show that ferromagnetism originated from the doped matrix and enhancement (suppression) of ferromagnetism is strongly correlated with the increase (decrease) of oxygen vacancies in TiO2.
