The Superconducting Electronics Group aims to contribute to innovative energy conservation through the superconducting technology. To realize them, we are promoting research and development for industrial applications of cuprate and iron-based high-temperature superconductors. We are also promoting the development of new superconducting materials with high superconducting transition temperatures, elucidating the mechanism of high-temperature superconductivity through theoretical and experimental approaches, and developing other new functional materials.
