摘要： This invention provides a magnetic optical member that can obtain a large magneto-optical effect using a rare-earth- iron-garnet-based material and a method of producing the same. According to the present invention, a BiYIG thin film (207) is formed on a (SiO 2 /Ta 2 O 5 ) n layer (210), and heat-treatment for crystallization of the BiYIG thin film (207) is carried out with infrared rays while cooling a non-heat-resisting substrate (203) and the (SiO 2 /Ta 2 0 5 ) n layer (210) through a substrate holder (201). Since the non-heat-resisting substrate (203) is cooled and the deformation thereof is prevented, heat treatment to crystallize the BiYIG thin film (207) can be carried out. By the crystallization of the BiYIG thin film (207) a large magneto-optical effect can be obtained. The non-heat-resisting substrate (203) is cooled, and can be made of a thermoplastic resin or can be formed in a tape shape, film shape or sheet shape. Thus, easy handling of the substrate and downsizing can be realized. Further, it is not necessary to make the substrate of glass, making it easy to form a groove. By the cooling of the (SiO 2 /Ta 2 O 5 ) n layer (210) the interdiffusion of Ta 2 O 5 and SiO 2 is prevented and heat treatment for crystallization can be performed.
