Abstract

890,754. Magnetic structures. GENERAL ELECTRIC CO. Ltd. April 25, 1960 [April 28, 1959], No. 14455/59. Class 38 (2). A magnetic thin film element formed by electrodeposition of 80/20 NiFe alloy on glass is formed or annealed in a magnetic field at an angle to the plane of the film. The film 2 is placed in a furnace 1 at an angle and between polepieces 3, 4 of an electromagnet, heated at 400‹ C. for one hour and allowed to cool. The " easy direction " is found to be the direction of the projection of the field vector in the plane of the film. It is found that the ooercivity in the " easy direction " is reduced by this process, thus facilitating the switching of the magnetization along this direction from one sense to the other.
