Abstract: In a process for heat treating amorphous magnetic alloys by producing a film composed of the amorphous magnetic alloy and heat-treating the film at an elevated temperature below the Curie temperature and the crystallisation temperature of the amorphous magnetic alloy using a first magnetic field and a second magnetic field which are repeatedly applied in an alternating manner, the first magnetic field is applied for a predetermined time in one direction of a principle surface of the amorphous magnetic alloy film and the second magnetic field is applied for a predetermined time in a second direction perpendicular to the first direction in the principle surface of the amorphous magnetic alloy film.
