ABSTRACT:
A magnetic head especially suited for digital signals has cores each of which consists of a composite material. This material is produced by preparing an alloy such as cobalt-iron alloy, iron-silicon-boron alloy, or nickel-silicon-boron alloy, to use it as the matrix of the composite material, then melting the matrix, spraying particles made of carbon, a nitride, an oxide, or other material against the molten matrix to disperse the particles in the matrix uniformly in a three-dimensional way, cooling the matrix to produce an ingot, and refusing the ingot such that the particles do not melt, and solidifying the ingot by rapid quenching.
