Growth of High-Quality Garnet Thin Films from Supercooled Melts

Abstract

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.
