CRYSTAL PRODUCTION METHOD FOR GALLIUM OXIDE-IRON MIXED CRYSTAL

摘要

A crystal production method for gallium oxide-iron mixed crystal (Ga2-xFexO3) allowing spin information buried in a solid to be read by using the magnetoelectric effect. The crystal production method for gallium oxide- iron mixed crystal is characterized in that a single crystal of Ga2- xFexO3 having a crystal structure of monoclinic system is produced by a floating zone melting method in which a floating zone is formed between tips of specimen rods of Ga2-xFexO3 vertically aligned by heating the tips in a gas atmosphere by means of heat sources arranged confocally. By this method, a high-quality, uniform, large Ga2-x FexO3 crystal is produced.
