Method of making magnetic film-substrate composites

摘要

Magnetic film-substrate composites of enhanced quality are provided by rotating a garnet substrate immersed in a melt of magnetic film material to obtain a growth of magnetic film having uniaxial anistropy on the substrate normal to the substrate surface and maintaining the immersed substrate stationary in the melt after a desired film growth has been achieved to effect enhancement of the anisotropy constant of the film.
