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. Electroanalytical parameters like reduction potential and current for the FePtP deposition were studied using cyclic voltammeter. Reasons for variation in magnetic and electroanalytical properties are discussed.
