摘要： There is provided a single crystal growth method which allows single crystal of an incongruent melting compound to be grown stable while controlling its growth orientation. The single crystal growth method comprises the steps of: holding polycrystal and seed crystal within a heating furnace; joining the polycrystal with the seed crystal; heating the polycrystal on the side opposite from the side where the polycrystal is joined with the seed crystal to form a melt zone; moving the melt zone to the side where the polycrystal is joined with the seed crystal so that the melt zone is in contact with the seed crystal to allow seeding; and growing single crystal by moving the melt zone which has been in contact with the seed crystal and been seeded to the opposite side from the side where the polycrystal is joined with the seed crystal.

摘要： The present invention provides a cerium-containing magnetic garnet single crystal having a size enough to use as a material for optical communication of an isolator and for an electronic device, and a producing method thereof.
The cerium-containing magnetic garnet single crystal of the present invention is obtained by melting a cerium-containing magnetic garnet polycrystal while applying a sharp, large temperature gradient to the solid-liquid interface of a melt and a solid, and then solidifying the melted polycrystal. The polycrystal is preferably heated by using an optical heating device, for example, a combination of a main heating device using a laser beam, and an auxiliary heating device using reflected light from a halogen lamp.摘要翻译： 本发明提供一种具有足以用作隔离器和电子器件的光通信材料的尺寸的含铈磁石榴石单晶及其制造方法。 本发明的含铈磁石榴石单晶是通过熔融含铈磁性石榴石多晶体，同时对熔体和固体的固 - 液界面施加急剧的大温度梯度，然后使熔融的多晶体 。 优选通过使用光学加热装置，例如使用激光束的主加热装置和使用来自卤素灯的反射光的辅助加热装置的组合来加热多晶体。
