Abstract
Special sputtering methods have been used to synthesize magnetic films that exhibit high intrinsic coercive forces iHc, large remanent moments, and special anisotropies. By special anisotropies we mean that the easy direction of magnetization in various films can be made to be either in or out of the film plane or in a particular direction within the film plane. To achieve high coercive forces in the films it has been necessary to synthesize the films from high iHc rare-earth transition metal systems such as SmCo5, Nd2Fe14B, and several new compounds in the Sm-Ti-Fe system. Films have been synthesized with different crystal textures by varying the sputtering parameters. The magnetic properties observed have been found to be strongly dependent on the film texture. Several possible film scale geometries for electronic applications have been considered.
