· Journal of Applied Physics, 97:046103
Epitaxial ferromagnetic films of Cr-doped TiO₂ anatase (CrxTi₁-xO₂-x/₂) were grown on LaA1O3(001) using oxygen-plasma assisted molecular beam epitaxy. Cr K-shell x-ray absorption near-edge spectroscopy shows that the formal oxidation state of Cr is +3 throughout the films with no evidence for either elemental Cr or half-metallic CrO₂. Cr is found to substitute for Ti in the lattice with uniform distribution throughout the doped region of the film. The Cr-doped anatase films exhibit room temperature ferromagnetism aligned in-plane with a saturation magnetization of ~0.6 µB/Cr atom.
