In this investigation, the influence of Fe-doping on the structural, elemental, micro structural and magnetic properties of the films has been studied. The structural properties of the films were investigated by using the X-ray diffraction (XRD). From the XRD analysis, it was observed that the doping concentration has a significant effect on crystalline quality and grain size of the films and all the films showed single phase with hexagonal structure. The composition analysis was determined by energy dispersive spectroscopy (EDS), and all the deposited films exhibited nearly stoichiometry. Evidence of nano crystalline nature of the films was observed from the investigation of surface morphology using atomic force microscopy (AFM). The films exhibited smooth fine grainy surface. The magnetic field dependence of the magnetizations was measured by VSM. Fe doping converts diamagnetic CdS into ferromagnetic and the results showed that the Fe doped CdS thin films can be employed in the fabrication of the nanoscale magnetic devices.
