The 247th Topical Symposium of the Magnetics Society of Japan

Recent progress in magnet development focused on recycling techniques and rare-earth-free magnets

Recently, the supply risk of rare earth elements used in neodymium magnets has garnered renewed attention. Efforts are actively underway to reduce rare earth usage, including the development of rare earth-free magnets, and promote rare earth recycling in magnet, and further development is expected in the future. In this topical symposium, we invite seven outstanding lecturers in this research field. We look forward to your active participation.
