Abstract

The magnetic film of Ferrous Tungsten Phosphorous (Fe-W-P) were prepared with NaH2PO2 and H3PO3 by electrodeposition method for current density of 30 mA cm−2 and 45 minutes deposition time. The magnetic saturation (Ms), retentivity (Mr) and coercivity (Hc) of the films were studied using vibrating sample magnetometer. The retentivity (Mr) and the magnetic saturation (Ms) of the deposited films increased with the increase of organic additive. The crystallite size and stress of the deposited thin films were calculated using X-ray diffraction (XRD) studies. Percentages of elemental analysis of Fe-W-P films were obtained using energy dispersive X-ray analysis (EDAX). Surface morphology analysis was carried out using scanning electron microscope (SEM). The magnetic properties and structural characteristics of Fe-W-P thin films with NaH2PO2 and Fe-W-P thin films with H3PO3 are discussed..
