The study of magnetic and microstructural characteristics of some nanostructured magnetic thin layers have fundamental importance to understand magnetization dynamics and is related to applications in micro electro mechanical system applications. This paper is devoted to the investigation of FePt alloy films by electrodeposition technique. High quality of deposit with low cost is the advantage of this technique. Structural analysis of the film was carried out using X-ray diffractometry & scanning electron microscopy. Elemental compositions of the film were studied using energy dispersive X-ray spectroscopy. Magnetic properties were studied using vibration sample magnetometer. The surface morphology, crystalline structure, grain size and magnetic properties of the plated films have been compared. The × ray analysis and magnetic measurements reveal the presence of hard and soft magnetic phase with various temperature for dc plated films. Thickness was measured by using digital micrometer. Hardness and adhesion of the film were also studied. Testing results shows that magnetic and structural properties depends upon the bath temperature, current density, annealing and composition ratio of Fe and Pt. Films are shiny and smooth. Reasons for variation in magnetic properties and structural characteristics were discussed.
