ABSTRACT:
Disclosed is a soft-magnetic film having high saturation magnetic-flux density. The soft-magnetic film is made of an alloy containing as its main components Fe, Co and Ni in the proportion: 20%<Fe<75%, 5%<Co<45% and 20%<Ni<70% (at %) and has a structure in which (110) or (111) planes of a face-centered cubic-lattice structure are given to its thin-film surface, as a preferred crystallographic orientation. The thin-film alloy may contain less than 5% of Cr, Ti, Zr, Hf or the like. The thin film of this alloy is formed by evaporation, electroplating or the like.
