Abstract (in Japanese) (See Japanese page) 
(in English) Magnetic garnet films such as bismuth, dysprosium, and aluminum substituted yttrium iron garnet (Bi:YIG) are used for rewritable magnetic hologram. The diffraction efficiency depends on the Faraday rotation angle and is in proportion to strength of magnetization of the magnetic film. However, the diffraction efficiency is not enough high as expected from the calculation because the magnetization at the heated region may not be completely reversed. To improve the diffraction efficiency, magnetic assist recording method would be effective because it can enhance the intensity of reversed magnetization. In this study, we investigated the effects of magnetic assist recording through numerical simulation and experimentally obtained diffraction efficiency of Bi:YIG.
