Electronic Structure and Magnetic Properties of Iron Doped TiO₂ (Rutile): XPS Measurements and CPA Calculations

Abstract:

X-ray photoelectron spectra of TiO₂:Fe are measured. Electronic structure and magnetic properties of rutile doped by iron are calculated in frames of the coherent potential approximation. The main experimental spectral features of TiO₂:Fe such as heterovalent cation substitution (Fe³⁺→Ti⁴⁺), decreasing of the band gap value and appearance of additional features at the bottom and top of X-ray photoelectron spectra of valence band in comparison with those for undoped TiO₂ are described.
