A comparative study of sodium hypophosphite and phosphorous acid on the Ferrous Tungsten Phosphorous thin films

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 (M-s), retentivity (M-r) and coercivity (H-c) of the films were studied using vibrating sample magnetometer. The retentivity (M-r) and the magnetic saturation (M-s) 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.
