Abstract

Fe xTi 1-xO 2 rutile films with x=∼-0.07 were grown by oxygen-plasma assisted molecular beam epitaxy (OPA-MBE). The films showed island growth on an otherwise flat rutile film surface. The islands were found to consist of clusters with TiO 2 and crystalline Fe 3O 4. The ferromagnetic behavior at room temperature was explained by the presence of Fe 3O 4 nanoparticles in the films.
