Abstract :

The saturation magnetization of Fe₇₀Co₃₀:Pd films and that of Fe₇₀Co₃₀ sublayers in [Fe₇₀Co₃₀-Pd]_n super-lattice films with various Fe₇₀Co₃₀ and Pd sublayer thicknesses are investigated. The saturation magnetization of these films was increased by alloying or laminating Fe₇₀Co₃₀ with Pd and the Fe₇₀Co₃₀:Pd and super-lattice films revealed high-saturation magnetizations of 2.45 and 2.57 T, respectively, while the saturation magnetization of Fe₇₀Co₃₀ film was only 2.38 T at room temperature. These results seem to be caused by the enhancement of the magnetic moment of the Fe atoms neighboring Co and Pd atoms.
