Abstract
A semiconductor magnetic head in which a polycrystal thin film of a semiconductor material containing at least a crystal particle having a longitudinal diameter of at least 30 .mu.m is employed as a magneto-sensitive element is disclosed. The semiconductor thin film containing the crystal particle of the longitudinal diameter at least 30 .mu.m can be easily formed with a good reproducibility by evaporating the semiconductor material on an insulation film containing not less than 3 mol % of alumina and then being subjected to a zone melting treatment.
