A method of manufacturing an amorphous alloy involves thermally treating or annealing the amorphous alloy material at a temperature lower than the crystallization temperature thereof through rotation of the alloy material relative to a magnetic field at a velocity so as to meet the following relationship: R tau O=0.5n where R is the number of revolutions per minute, tau O is an average time required to cause the amorphous alloy material to reach a thermal equilibrium state of induced magnetic anisotropy, and n is an integer of at least 1. The amorphous alloy thus prepared possesses a high permeability and a high saturated magnetic flux so that it is suitable as a soft magnetic core material, such a magnetic heads. |
