Physical Analyses of Magnetic Materials
JFE-TEC analyzes and evaluates matters ranging from macro structure factors including chemical composition, crystalline phase and crystalline orientation, which have an influence on the magnetic characteristic of hard magnet (permanent magnet) such as neodymium magnet and ferrite, to nano structure factors including element intercrystalline segregation of intercrystalline interface and intercrystalline phase.
Concerning soft magnetic materials including silicon steel sheet, we also undertake structure analysis necessary for magnet material design and failure analysis.
