 This four-year long research project funded by the Japanese government focused on exploring new superconducting materials and related functional materials. Over 1,000 materials were examined, all selected by Japanese experts, with experience in solid state chemistry. The project yielded several dozen new superconductors, as well as fabricated wire and tape made from iron based superconductors. Additionally, the project identified numerous new functional materials and their corresponding properties.
