特殊的溅射方法已被用来合成具有高内禀矫顽力iHc、大剩磁矩和特殊各向异性的磁性薄膜。所谓特殊各向异性，是指各种膜中的易磁化方向可以位于膜平面内或膜平面外，或者位于膜平面内的特定方向。为了在薄膜中获得高矫顽力，有必要从高 iHc 稀土过渡金属体系（例如 SmCo5、Nd2Fe14B 和 Sm-Ti-Fe 体系中的几种新化合物）合成薄膜。通过改变溅射参数，合成了具有不同晶体结构的薄膜。已发现观察到的磁特性强烈依赖于薄膜纹理。已经考虑了用于电子应用的几种可能的薄膜尺寸几何形状。
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.
