· JVASP-9112· HoNi3

HoNi3 is an intermetallic compound composed of holmium and nickel, belonging to the rare-earth metal family of materials. This compound is primarily of research and academic interest, studied for its magnetic and crystallographic properties rather than widespread industrial production. It represents the type of rare-earth intermetallic systems explored for specialized applications in magnetism and materials physics, though practical engineering use remains limited compared to more conventional superalloys or permanent magnet materials.
