TB-CONTAINING RARE EARTH-ALUMINUM GARNET CERAMIC, AND METHOD FOR MANUFACTURING SAME
[Problem to be solved] To provide a Tb-containing rare earth-aluminum garnet ceramic which has a Verdet constant similar to that of a TGG single crystal used in an isolator, has an insertion loss and extinction ratio equal to or greater than those of a TGG single crystal, generates less heat when a high-power laser is applied thereto, and is unlikely to cause a thermal lens effect or thermal birefringence.[Solution] The present invention relates to: a Tb-containing rare earth-aluminum garnet ceramic including a garnet polycrystal represented by the compositional formula (TbxRe1-x)3(AlySc1-y)5O12 wherein Re is at least one element selected from a group consisting of Y and Lu, x=1.0-0.5, and y=1.0-0.6, and including Si and at least one element selected from a group consisting of Ca and Mg; a method for producing same; and an isolator device obtained using the ceramic.
