Abstract
An amorphous magnetic film is produced by irradiating laser beams onto a magnetic metallic target and depositing an evaporated material on a substrate. During or after the evaporation process, the film formed on the substrate is annealed at a temperature lower than a crystallization temperature. The annealing process enables elimination of stresses from the film, thereby improving soft magnetic properties.
