Abstract
A soft magnetic film has a composition represented by the formula FeXCoY&agr;Z wherein &agr; is at least one element selected from the group consisting of Rh, Pd, Pt, Ru, and Ir and X+Y+Z=100 mass percent. The ratio X/Y by mass percent of Fe to Co is in the range of 2 to 5, and the &agr; content Z is in the range of 0.5 to 18 mass percent. This alloy exhibits a saturation magnetic flux density of at least 2.0 T and high corrosion resistance.
