Title: Zn interstitial defects induced magnetic nature in Fe ions doped ZnO based DMS

This paper describes the synthesis of Fe doped ZnO samples Zn{sub 1-x}Fe{sub x}0, where x various from 0.01≤x≤0.05 (in steps of 0.01) by solution method. The effect of Fe ions doping on the structural, optical and magnetic properties was investigated using X-ray diffraction (XRD), Photoluminescence and vibrating sample magnetometer (VSM) measurements. The observed result indicates that the samples are single phase formation of the wurtzite structure without any significant secondary phase in it. The photoluminescence spectra reveals the presence of Zn vacancies. The magnetic property of prepared samples was studied using a vibrating sample magnetometer and the observed results revealed a super-paramagnetic behavior for the Fe doped ZnO samples.
