In this research thin films of FePt alloy with different percentages of iron, were electrodeposited on Cu and Au substrate in CHC mode under constant potential in single electrolytic bath. Cyclic voltametry identified the using starting voltage of deposition of alloy layers. Then, FePt/Pt multilayers with different thicknesses of platinum layers were deposited on the Cu and Au substrates. The effect of thickness on the surface morphology of the layers was studied. In this work, crystalline structure and morphology of FePt alloy and FePt/Pt multilayers have been studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Energy dispersive X-ray analysis (EDX) has determined weight and atomic percentages of the elements in the deposited layers. Magnetic properties of the alloy deposited on Au substrate have been studied using the alternating gradient force magnetometer (AGFM).
