Abstract
Single doped Zn1−xMnxO, Zn1−xFexO and codoped Zn1−x−yMnxFeyO, Zn1−x−yMnxSnyO, Zn1−x−yMnxLiyO, Zn1−x−yFexAlyO thin films were grown on sapphire and glass substrate by pulsed laser deposition and RF sputtering techniques. No secondary phases was detected from XRD analysis. Among the studied oxide films single doped with Fe and codoped with (Mn,Fe) and (Fe, Al) exhibit n-type conductivity and room temperature ferromagnetic behaviour. For the films codoped with (Mn, Sn) formation of clusters including nanowire-like structures was shown from AFM analysis. Optical and magnetooptical studies suggest of Mn, Fe, Sn and Li substitution for Zn2+ ions in ZnO lattice.
