Growth of High‐Quality Garnet Thin Films from Supercooled Melts

A new dipping technique is described for producing uniform‐thickness low‐defect‐density magnetic garnet films suitable for bubble‐domain devices. The technique is based on the observation that melts having the appropriate flux and garnet composition can be supercooled over a large temperature range and will remain supercooled, permitting the growth at constant temperature of epitaxial magnetic garnet films.
