Abstract

PURPOSE:To provide a soft magnetic thin film of good magnetic properties by specifying a composition range of FeCoNi alloy. CONSTITUTION:A soft magnetic thin film, mainly consisting of FeCoNi alloy of Fe, Co and Ni in the composition range of Fe of 20-40 atomic %, Co of 15-55 atomic % and Ni of 20-55 atomic %, has good magnetic properties when used as a single layer film. Moreover, by laminating this soft magnetic thin film as the first soft magnetic thin film onto the second soft magnetic thin film of body-centered cubic structure, the magnetic properties can be improved still further. When such a soft magnetic thin film of single layer type or laminated layer type is used, for instance, for a core material of magnetic head, excellent recording and reproduction can be realized.
