PEPM2025 Program Booklet (PDF: 13MB)
More than 220 abstracts have been submitted to REPM 2025 from 22 countries represented by 69 different cities. This highlights an interest and global efforts in permanent magnet research which are as high as ever. Once faced with the rare earth crisis in 2010, society keeps struggling with other challenges including supply chain risks, climate changes and geopolitical tension. As various nations begin to diversify the production of rare earth permanent magnets and accelerate the transition to green energy, the responsibility of scientific community is to conduct basic research and innovations on permanent magnets that can facilitate this process and ensure a sustainable future. We look forward to lively debates, new collaborations, and breakthroughs on permanent magnets and their applications.
