ABSTRACT:
The magnetic bias field required to collapse magnetic domains in an epitaxial liquid phase grown garnet is reduced by a method of depositing a layer of a suitable element, e.g. gallium or chromium, on the surface of the garnet after growth and then heating the garnet. The suitability of the element depends on its atomic diameter and affinity for oxygen.
Propagation paths for bubbles in a magnetic bubble memory are defined by treating a garnet except where the propagation paths are required, by the method.
