Paper Abstract

The microstructure, optical properties, and magnetic properties of Fe-doped ZnO thin films prepared by direct current (DC) magnetron sputtering were studied in detail. The chemical composition were examined by Energy Dispersive x-ray Spectroscopy (EDS) and the charge state of Fe ions in the ZnO:Fe thin films was characterized by X-Ray photoelectronic spectrometry (XPS). X-ray diffraction (XRD) characterization of ZnO:Fe thin films confirmed the exclusive formation of the films with the wurtzite structure. The optical transmittance of the films decreased with the increasing of the iron concentration. Room-temperature magnetic measurements indicated that all the films are not ferromagnetic above 50 K. The effect of Fe doping was discussed and relevant mechanism was proposed by comparing with previous studies in ZnO systems.
