PURPOSE:To eliminate the need for removal of a substrate consisting of a required material by growing prescribed magnetic films in a liquid phase on both faces of said substrate. CONSTITUTION:Magnetic films 2, 2' consisting of Lu3-xBixFe5O12 (where 0.5<x<0.7) are formed by the liquid phase growth method on both the front and rear surfaces of the transparent substrate 1 which consists of Gd3Ga5O12 and does not absorb light. The magnetooptic element is thus formed in the short time for crystal growth without the need for polishing and removing the substrate 1.
