Disclosed is a ferromagnetic film consisting of an alloy represented by a formula CoxFeyTz, where T is an element selected from the group consisting of Ta, Ti, Zr, Hf, Mo, and W, and x, y, and z represent atomic % and satisfy 73<x<94, 5<y<15, 1<z<12, and x+y+z=100. 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.
