Development of Soft Magnetic Materials and Magnet Consisting of Complete Rare-Earth Free Elements Both with Ultimately-High-Efficient Types Contributing to Energy- and Resource-Saving by Precise Controlling their Nanostructures
update：2020-06-16
Research activities include high functionalization and attachment of additional values to the soft magnetic materials of iron-group based metallic glasses, nanocrystalline and amorphous alloys and magnets, both from non-equilibrium alloys with useful properties that have not been achieved by conventional crystalline alloys. Recent successful results contain newly-developed nanocrystalline soft magnetic alloys with high saturation magnetic flux density of 1.8 Tesla or higher and low core loss of ~1/3 to that of the Silicon steels and fabrication of rare-earth free L10-FeNi magnets.
Possible Academic/Industrial Collaborations
The target materials possess high potential as industrial materials owing to Fe-based alloy with low material costs accompanied by rare-earth-free nature and to producibility in an air environment. Expectations are contributions to energy-saving, saving mineral resources and reducing carbon dioxide emissions through collaborations with companies dealing with materials and applications.
