A world center dedicated for research and development of novel high-performance permanent magnets free of critical scarce elements.

 Elements Strategy Initiative Center for Magnetic Materials(ESICMM) put its goals on (1) laboratory-scale synthesis of mass-producible high-performance permanent magnets free of critical scarce elements for the next generation and (2) framework-building and provision of basic science and technology that are needed in industrial R&D activities. For these goals, ESICMM focusses on theoretical search and mining of new permanent magnet materials, and simultaneously pursue every possibility of processing technology to improve the existing high-performance permanent magnet materials through cooperative activities in three research fields of computer physics, structural and property characterization, and material processing. Another important mission of ESICMM is to edify scientists who will contribute to sustain future developments in magnetic functional materials.

Research Groups

●Electronic Theory and Computation Group

 The group aims at development of theory of magnetic reversal phenomena and theoretical exploration of next-generation permanent magnet materials free from scarce resources by use of first-principles methods and statistical approaches. The research topics include high-accuracy calculation of magnetic quantities from first-principles, large-scale simulation of interfaces/surfaces, Laudau-Lifshitz-Gilbert simulation starting from atomistic models, and temperature and materials dependences of magnetic properties.

●Structural and Property Characterization Group

 The aim of the Structural and Property Characterization Group is to obtain guiding principles for developing high coecivity permanent magnets by understanding the structure-property relationships of hard magnetic materials. For this purpose, we perform multi-scale characterizations of microstructures and magnetic structures by employing state-of-the-art microscopy techniques including SEM, STEM and 3D atom probe. To obtain averaged structural information, diffraction, scattering and spectroscopy experiments using the synchrotron x-ray source at Spring-8 and the neutron source at J-PARC. To complement the direct microscopic magnetic imaging, we also perform large scale parallel computations to run finite element micromagnetic simulations for complex model structures tha are close to actual microstructures of permanent magnets using K-computer.

●Materials Symthesis and Processing Group

 Materials Symthesis and Processing Group sets its goal on an innovation in materials processing, aiming at enhancing the magnetic properties and developing the next generation magnets based on integrated techniques of microstructural control, thin film technique and build-up process in nanoparticles. We also cooperate with the electronic theory group and the analytical characterization group to share our results and refer information from theories, simulations and analyses.
