ABSTRACT:
A magnetic head is disclosed which has a metal magnetic film formed by first stacking Fe--M--N magnetic thin film layers and precious metal layers such as Pt layers to form a multilayer film and then stacking such multilayer films via an insulating film so that the reproduction output is improved to make the magnetic head suitable for recording on and reproduction from a magnetic recording medium having a large coercive force, such as, a so-called metal tape. On gap forming surfaces of a pair of magnetic core halves, a multilayer structure formed by first forming a multilayer film by stacking magnetic thin film layers having composition of Fe.sub.x M.sub.y N.sub.z (with M being at least one selected from Ta, Zr, Hf, Nb, Ti, Mo and W, and x, y and z indicating atomic percentage and holding relations of 71.ltoreq.x.ltoreq.85, 6.ltoreq.y.ltoreq.15, and 9.ltoreq.z.ltoreq.16) and layers made of at least one selected from Pt, Au, Ag and Pd, and then stacking such multilayer films via at least two layers made of any one of SiO.sub.2, ZrO.sub.2, Al.sub.2 O.sub.3 and Cr.
