I gave a presentation at the "Committee for Research on the Creation and Device Applications of Nanoscale Soft Magnetic Materials" of the Institute of Electrical Engineers. If you would like the presentation materials, please download them. <Content> ■ Background of the research and challenges in current measurement ■ Structure and characteristics of the optical probe current sensor (OpECS) ■ Magnetic materials used in optical probe current sensors ■ Research and development of novel magneto-optical thin films and granular films ■ Research and development of the magneto-optical crystal Bi:RIG ■ Research and development of metal composite magnetic yokes

We have created the 2022 company brochure for Citizen Fine Devices Co., Ltd. It covers all of our technologies and product introductions, so we kindly ask you to take this opportunity to download it.
