Different composition FeNi films were prepared through electrodeposition. The surface morphology and structure of films were analyzed. The magnetization curve and magnetic hysteresis of samples were measured. The results indicate that the Fe-Ni films with crystal structure can be prepared through electrodeposition. The Fe-Ni films of different chemical compositions possess different preferred orientation. The magnetic performances vary with Ni mass fraction. The maximum permeability of electrodeposited Fe-Ni films is superior to the cold-rolled 1J85 alloy in open circuit measurement.
