The research community in the field of spintronics in Japan applied for the “Master Plan 2014” of the Science Council of Japan and was selected from a large number of applications (224 in all). In addition, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) reviewed 27 proposals for this Master Plan, and 10 of them, including the proposal in the field of spintronics, were selected for the “Roadmap 2014 – Major Projects for Academic Research”. In this project, the “Center for Spintronics Research Network (CSRN)” has been established at the hub universities (Tohoku University, the University of Tokyo, Keio University, and Osaka University) to connect major universities, national laboratories, related companies, and other leading research institutions in Japan. On the occasion of reselection for inclusion in “Master Plan 2020” and “Roadmap 2020”, the CSRN was also established in the Institute for Chemical Research, Kyoto University to strengthen the international collaboration along with the other four core universities. By linking major universities, national research institutes, related companies, and other leading research institutes in Japan, the CSRN works to enhance Japan’s research capabilities and industrial competitiveness, to bring about technological innovation, and to foster the next generation of researchers and engineers.
