GROWTH AND PROPERTIES OF THIN SINGLE CRYSTAL FILMS OF YTTRIUM IRON GARNET.

Abstract

Techniques were developed to grow single crystal films of a magnetic garnet (yttrium iron garnet) on a nonmagnetic garnet substrate. A number of substrates were investigated, including Y3Al5012, Gd3Ga5012, and Y3(GaxIn1-x)5012. It was found that Gd3Ga5012 (which matches YIG in lattice constant) could be grown as large, relatively perfect crystals by the Czochralski technique. YIG films were grown by flux and vapor deposition. The perfection, optical transmission, surface characteristics, and thickness of these films were investigated. (Author)
