Creative Lab. for Advanced Spin Systems (CLASS) aims at the fundamentals and application of magnetic materials. Especially focus on the fundamental understanding of magnetic spin structure in sub-nanometers and applying magnetic spin structure to a spintronic device for memory and next-generation intelligent semiconductors. In addition, we are developing rare-earth-free permanent magnets, eco-friendly materials using magnetic particles, and a new concept of three-dimensional printing technology.
