<p>PURPOSE:To obtain excellent temp. characteristics by joining >=2 kinds of rare earth iron garnet polycrystal bodies which are different in dependency of coefft. of Faraday rotation on temp. CONSTITUTION:Not less than 2 kinds of the rare earth iron garnet polycrystal bodies which are different in the dependency of the coefft. of Faraday rotation on temp. are joined. For example, the rare earth iron garnet polycrystal body is preferably the polycrystal body expressed by the formula R3M5O12. In the formula, R denotes at least one kind of element selected from Bi, Y rare earth element and at least one kind of element selected from Ca, Ba, Mg, and Sr, M denotes at least one kind of element selected from Al, Sc, Ga, Zr, Ge, Si, Ti, V, In, Sb, and Sn. A magneto-optic element having the excellent temp. characteristics is thus obtd.</p> |
