Thin films of ilmenite-hematite solid solution, Fe1.4Ti 0.6O3 were prepared on α-A12O3 (001) and (110) single-crystalline substrates by reactive helicon plasma-sputtering technique. The oxide phases formed in the thin films and the degree of cation ordering in the ilmenite phase strongly depended on the preparation conditions. At the optimized preparation conditions, regardless of the substrate orientation, well-ordered Fe1.4Ti0.6O 3 films with R3 symmetry were epitaxially formed on the substrates. Large saturation magnetization at room temperature was observed in both (001)- and (110)-oriented films. The ordered Fe1.4Ti0.6O 3 films were ferrimagnetic semiconductors at room temperature. The (110)-oriented film had uniaxial in-plane magnetic and electric anisotropies, because Fe1.4Ti0.6O3 had a magnetic easy plane and predominant conduction in the (001) crystallographic plane. The differences in magnetization and electrical resistivity curves between the (001)- and (110)-oriented films indicated the anisotropic nature of Fe1.4Ti 0.6O3.
