Abstract

Ferromagnetic Cr-doped rutile TiO2 single crystals were synthesized by high-temperature ion implantation. The associated structural, compositional and magnetic properties were studied by X-ray photoelectron spectroscopy, Rutherford backscattering spectrometry, proton induced X-ray emission, X-ray diffraction, Cr K- and L-shell near-edge X-ray absorption spectroscopy and vibrating sample magnetometry. Cr was distributed uniformly to the depth of about 300 nm with an average concentration of ∼1 at.%. The samples are semiconducting and ferromagnetic as implanted, with a saturation magnetization of 0.29μB/Cr atom at room temperature. Cr is in a formal oxidation state of +3 throughout the implanted region and no CrO 2 is detected.
