Structural, optical and magnetic characterisarion of pulsed laser deposited thin films of Zn1-xMxO (M= Mn, Fe, Ni, Cu) transparent magnetic alloys.

2009

Zn1-xMxO (M = Mn, Fe, Ni, Cu) films were deposited at optimal conditions over mica and sapphire substrates by laser ablation of polycrystalline targets containing stoichiometric mixtures of chemical compounds. These films were then characterised structurally, electronically, optically and magnetically. The structural characterisation was done by plume emission spectroscopy, XRD, XAS, XRF, electron microscopy and microanalysis to ensure that the expected films had been correctly deposited. Results indicated a constant chemical composition during the growth process and the resulting films grown over sapphire were found to be c-oriented. Maximum dilute cation solubilities were determined at 15…
