ABSTRACT:
A magnetic garnet film for a magnetic bubble memory device in which parts of rare earth element and iron are replaced by predetermined quantities of Gd and Ge, respectively. The garnet film exhibits very small temperature-dependency of the bubble collapse field as well as high Curie temperature, whereby magnetic bubbles of very small diameter can be sustained and controlled with stability over a wide temperature range.
