由日本东京大学工学部、产业技术综合研究所以及31个民间团体组织的原子技术研究机构的科学家，最近开发出了当光照射时电学性质会发生急剧变化的新型光电材料。新材料是制造高性能磁体用的金属谱与钙、锰、氧相结合的化公物。将新材料冷却到液氮温度下，用光照射它时，其电阻 Researchers at Japan's atomic technology research institute organized by the Faculty of Engineering, the Institute of Industrial Technology Synthesis and the 31 civil society organizations at Tokyo University have recently developed new photovoltaic materials that undergo dramatic changes in electrical properties when exposed to light. The new material is made of high-performance magnets with the metal spectrum of calcium, manganese, oxygen combined with the public property. The new material is cooled to liquid nitrogen temperature, with light irradiation, its resistance
