ABSTRACT:
A soft magnetic film having a high saturation magnetic flux density and superior soft magnetic properties and capable of maintaining superior soft magnetic properties when worked to a magnetic head. The magnetic film is represented by the general formula of Fe.sub.x M.sub.y L.sub.z J.sub.u Q.sub.w, wherein M denotes at least one selected from the group of Ru, Cr, Ti, Mo, W and Rh, L denotes at least one selected from the group of Y, Hf, Zr, Ta and Nb, J denotes at least one of Al and Ga, Q denotes at least one of Si and Ge and x, y, z, u and w denote the proportions of respective atoms in atom %, and wherein the composition is given by 68.ltoreq.x<80, 3.ltoreq.y<12, 3<z<5, 0.ltoreq.u<10 and 10<w<25. The soft magnetic film is formed on non-magnetic or magnetic ceramics and worked into a magnetic head.
