Magneto-optic garnet. |
| 摘要 |
<p>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.</p> |
