CRYSTAL PRODUCTION METHOD FOR GALLIUM OXIDE;IRON MIXED CRYSTAL

摘要

A manufacturing method of a Ga2-xFexO3 crystal is provided which can form a superior, uniform, and large crystal. <??>By a floating zone melting method in which ends of material bars (3, 5), which are disposed at an upper and a lower position and which are composed of Ga2-xFexO3, are heated in a gas atmosphere with halogen lamps (6, 7) disposed at confocal areas so as to form a floating melting zone between the ends of the material bars (3, 5) which are disposed at the upper and the lower position and which are composed of Ga2-xFexO3, a Ga2-xFexO3 single crystal having an orthorhombic crystal structure is formed. <IMAGE>
