· JVASP-86750· DyFe2B2

DyFe2B2 is an intermetallic compound combining dysprosium (a rare-earth element) with iron and boron, belonging to the family of rare-earth transition metal borides. This material is primarily investigated in research contexts for permanent magnet and high-performance structural applications where the combination of rare-earth elements and boron can provide enhanced magnetic properties or improved hardness at elevated temperatures. Industrial adoption remains limited, but the material represents a candidate composition for next-generation permanent magnets (competing with or complementing NdFeB systems) and hard magnetic phases in composite materials.
