This paper reports a unique approach to the fabrication of FePtP films by electroplating technique which is especially interesting due to its low cost, high throughput and high quality of deposit. Effect of concentration of urea in the presence of sodium hyphophosphite was studied. Vibration sample magnetometric studies indicate that has favourable impact on the magnetic properties of these films. Elemental composition of the molecules was studied using energy dispersive X-ray spectroscopy. The result shows that the phosphorous content was found to be less than 10%. Morphology and structural properties were carried out using scanning electron microscopy and X-ray diffractometry. Reasons for variation in magnetic properties and structural characteristics are discussed. Mechanical properties such as residual stress, hardness and adhesion of the films were also studied.
