چکیده انگلیسی
The local micro-structure as well as the magnetic and transport properties of CrxGe1âx films prepared by means of magnetron sputtering have been investigated. Structural analysis shows that Cr atoms are situated in substitutional sites in the Ge lattice. Electrical transport properties indicate that Cr introduces a shallow acceptor level at 0.016Â eV from the valence band implying Cr substituting for Ge. The low temperature ferromagnetism observed in the films is mediated mainly by ferromagnetic superexchange interactions between diluted Cr ions.
