CoPt 3 and FePd thin films have high magnetic anisotropy and high saturation magnetization and are suitable candidate for high-density magnetic recording. Achieving the best structure with optimal magnetic properties depends on the conditions of film deposition. The substrate, substrate temperature, post-annealing temperature, film’s thickness and ratio the elements are the most important factors which influence the structural and magnetic properties of the deposited films. In this project, CoPt 3 and FePd films were deposed using pulsed laser deposition. The magnetic hysteresis loop of the films was measured by the magneto-optical Kerr effect. Generally, the films deposited on MgO, fused-silica, Si and quartz substrates. In all cases, easy magnetic axis of the FePd was in-plane. The effect of post-annealing temperature, annealing in hydrogen and changing the Fe:Pd ratio were also investigated. As the post-annealing temperature for the FePd/MgO increased, the coercivity increased. Annealing in hydrogen also contributed in increasing the coercivity. Also, the coercivity of 60% Pd-40% Fe was higher than 50-50%. For CoPt 3 film, the effect of annealing, ratio of elements, coating layer and thickness were investigated. For CoPt 3 film, perpendicular magnetic anisotropy was observed under two conditions on MgO substrate. First, deposition at 500 ° C. Second, deposition at room temperature following with post-annealing at 500 ° C. The maximum perpendicular anisotropy was found by the deposition at 500 ° C with for a film with 5 nm thickness. In this case, a high coercivity about 6575 Oe was obtained. Also, deposition on other substrates showed that the films have in-plane anisotropy.
