Fujitsu and NIMS Develop Magnetic-Reversal Simulator to Foster Strong Neodymium Magnets
TOKYO: Fujitsu Limited announces the development of largest magnetic-reversal simulation using a mesh covering more than 300 million micro-regions. The latest development is the outcome of a joint research conducted by National Institute of Material Science (NIMS) and Fujitsu Laboratories.
The new development is built on the large scale magnetic reversal simulation technology and offers faster calculation algorithm andefficient parallel processing. The simulations can run on K computer, a high-performance computer developed by RIKEN and Fujitsu. Leveraging the technology, Fujitsu has examined the process of magnetic reversal in neodymium magnets by conducting a large-scale simulation to illustrate the correlation between fine structures of neodymium magnets and magnetic strength. The results have paved way to develop high-strength neodymium magnets with more than double coercivity of previous magnets without dysprosium.
The Ministry of Education, Culture, Sports, Science and Technology's "Elements Strategy Initiative Project", carried out at NIMS in the Elements Strategy Initiative Center for Magnetic Materials, aims at developing neodymium magnets that require no dysprosium by 2017.
