- Аннотация: We report an experimental study on transversal Kerr effect (TKE) in magnetic oxide semiconductors TiO2-delta:Co. The TiO2-delta:Co thin films were deposited on LaAlO3 (0 0 1) substrates by magnetron sputtering in the argon-oxygen atmosphere at oxygen partial pressure of 2 x 10(-6)-2 x 10(-4) Torr. It was obtained that TKE spectra in ferromagnetic samples are extremely sensitive to the Co-volume fraction, the crystalline structure, and technology parameters. The observed well-pronounced peaks in TKE spectra for anatase Co-doped TiO2-delta films at low Co (<1%) volume fraction are not representative for bulk Co or Co clusters in TiO2-delta matrix that indicates on intrinsic ferromagnetism in these samples. With increase of Co-volume fraction up to 5-8% the. ne structure of TKE spectra disappears and magneto-optical response in reflection mode becomes larger than that for thick Co films (C) 2008 Elsevier B.
