Abstract

Cu and P were examined as additives to decrease the perpendicular coercivity of Fe-electrodeposited alumite film. Addition of Cu and P to the Fe particles decreased the coercivity to less than 1000 Oe, and P was a more effective additive than Cu in decreasing the coercivity. In the Fe-Cu system, Cu atoms are considered to be dispersed uniformly in the Fe matrix because no drastic changes in the morphological, crystallographical and magnetic properties were observed. In the Fe-P system, P is considered to be precipitated between Fe microcrystallites because the crystallographic continuity of the Fe particles was deteriorated, and distinct microstructure was observed in the Fe particles when P was added. Drastic decrease in the coercivity of Fe-electrodeposited alumite film is considered to be mainly due to the discontinuity of the Fe particles in a system containing P.
