【発明の名称】磁気光学ガーネット
Document Type and Number:
Japanese Patent JP2679083
Kind Code:
B2
Abstract:
This invention provides a magneto-optic garnet grown by liquid phase epitaxy on a nonmagnetic garnet substrtae and hving a composition of formula (1) HoxTbyBi3-x-yFe5O12 wherein 0.3=y/x=1.0 and x+y< 3.0. The magneto-optic garnet can be used as a Faraday rotator in, for example, an optical isolator or optical circulator, since it has a very large Faraday rotation coefficient, differs little in lattice constant from a nonmagnetic garnet substrate, exhibits a mirror face without film defect (or pit), and has a small temperature dependency.
