Magneto-optic garnet |
| 摘要 |
This invention provides a magneto-optic garnet grown by liquid phase epitaxy on a nonmagnetic garnet substrate and having a composition of the following formula (1) HoxTbyBi3-x-yFe5O12 (1) wherein 0.3</=y/x</=1.0 and x+y<3.0. According to this invention there is provided a magneto-optic garnet as a Faraday rotator for use in an optical isolator, optical circulator, etc., utilizing Faraday effect, which has a very large Faraday rotation coefficient, a small difference in lattice constant from a nonmagnetic garnet substrate, exhibits a mirror face without causing a film defect (or so-called pit), and has a small temperature dependency.
