Single Crystals of Yttrium and Rare Earth Gallium Perovskites for Use as Substrates for Bubble Domain Iron Perovskites.
Abstract
It has been shown that a number of rare earth gallium oxide perovskites can be synthesized at normal pressure and temperatures exceeding 1650 C. Single crystals of NdGaO3 suitable as substrate for orthoferrites have been grown. The crystal structure of a newly found high temperature modification of YGaO3 has been determined. Thin single crystal epitaxial films of Sm0.55Tb0.45FeO3 have been grown on NdGaO3 substrates, but they have been too thin to sustain bubble domains. It is still believed that it should be possible to grow epitaxial orthoferrite films of suitable thickness on rare earth gallium oxide perovskite substrates.
