HoFe2B2
metal· JVASP-54995· HoFe2B2
HoFe₂B₂ is an intermetallic compound combining holmium, iron, and boron, belonging to the rare-earth iron boride family of materials. This compound is primarily of research and developmental interest for applications requiring the combination of magnetic properties from holmium and iron with the hardening and structural benefits of boron. While not yet widely established in mainstream industrial production, materials in this class are explored for specialized applications in high-performance magnets, hard coatings, and advanced structural components where the rare-earth–transition-metal–boride system offers potential advantages over conventional alternatives.
