Abstract

PURPOSE:To obtain an anisotropic thin magnet by inclining an evaporating heat source and a substrate to a prescribed angle and restricting the growth direction of the crystal of a magnet in evaporating a magnetic material on the substrate made from a nonmagnetic material as a magnet for a watch. CONSTITUTION:In an evaporation process, an evaporating heat source 7 and a substrate 8 are inclined to a proper angle determined by the property of an anisotropic magnetic material 9. The growth direction of a crystal of a magnet is determined primarily by this inclined angle, allowing anisotropy to be produced to provide a high energy product. Or, a magnetic field is provided near the substrate 8, and anisotropy is produced with evaporation. For a magnetic material 9, samarium.cobalt is used and is evaporated in vacuum under the Curie temperature of the magnetic material 9. The evaporation is made on both surfaces or the one side surface of the substrate 8 by using a mask 10. On the substrate 8, a base 12 having a hole 12a and a bridge 12b correspondingly to a rotor magnet 11 is formed by means of etching processing of a stainless plate, and after evaporation, the bridge 12b is punched out. Further, for the substrate 12, synthetic resin is used and is melted after evaporation, thereby allowing the magnet to be formed.
