ABSTRACT:
A magnetic head of the present invention has a magnetic core and a substrate for supporting the magnetic core. The magnetic core has a magnetic layer which is of a soft magnetic alloy mainly composed of FeTaN. The composition of the alloy meets 72.ltoreq.x.ltoreq.82, 5.ltoreq.y.ltoreq.15, 10.ltoreq.z.ltoreq.15 by atomic percent, where the alloy is indicated to be Fe.sub.x M.sub.y N.sub.z. The magnetic layer contains crystal grains of body-centered cubic structure, and each diameter of said crystal grains is less than 10 nm. The crystal grains have lattice planes which are orientated at random.
