ABSTRACT:
Disclosed is a ferromagnetic film consisting of an alloy represented by a formula (M.sub.a T.sub.b).sub.x N.sub.y, wherein M consists of Co and Fe, T is an element selected from the group of transition metals consisting of Ta and Nb, N is nitrogen, a, b, x, and y represent at % and satisfy 85<a<95, 5<b<15, a+b=100, 82<x<97.5, 2.5<y<18, and x+y=100, and the Fe content of M satisfies 2.5.ltoreq.Fe.ltoreq.12.5 at %. This ferromagnetic film has high saturation magnetic flux density, and soft magnetism not to be degraded by high-temperature annealing, and which is suitably applied to a magnetic head.
