A room-temperature ferromagnetism has been observed for oxygen-deficient rutile and anatase TiO<SUB>2 ? δ</SUB> films. XPS data revealed the existence of Ti<SUP>3+</SUP> ions, for compensating the charge imbalance caused by oxygen vacancies in the film. The observed ferromagnetism is attributable to the spin (3d¹) alignment of the Ti<SUP>3+</SUP> ions. Such spin alignment can happen through magnetic polaron formed by trapped electron in oxygen vacancy and magnetic Ti<SUP>3+</SUP> ions around it.
