摘要： A magnetostatic wave device has an external magnetic field applied in a direction that is substantially parallel to a plane of a thin film of a magnetic single-crystal having a garnet structure. The thin film of the magnetic single-crystal has an axis of easy magnetization that is oriented in substantially the same direction as the direction of the externally applied magnetic field.

摘要： A surface magnetostatic wave device includes an Fe-containing garnet single crystal film grown on a gadolinium gallium garnet substrate. The crystallographic plane azimuth of the gadolinium gallium garnet substrate can be one of a (110) plane, a (100) plane, and a (211) plane. The device achieves both a reduced saturation magnetization and a reduced anisotropic magnetic field to thereby minimize the lowest frequency in the propagation band.

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 large enough to use as a material for optical communication of an isolator and for an electronic device, and a production method therefor. 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 the melt and the 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.
