Abstract

FePtP films have been electrodeposited from a stable bath containing urea. By adjusting the current density and solution composition one can control the composition of the film. Effect of concentration of urea was studied. Vibration sample magnetometric studies indicate that urea has favourable impact on the magnetic properties of these films. Elemental composition of the molecules were 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..
