· JVASP-18934· HoNi2

HoNi₂ is an intermetallic compound composed of holmium and nickel, belonging to the rare-earth intermetallic family. This material is primarily investigated in research contexts for its magnetic and electronic properties, as the holmium-nickel system exhibits interesting magnetic ordering behavior at low temperatures. While not widely used in conventional engineering applications, HoNi₂ and similar rare-earth intermetallics are of interest in advanced materials research for specialized applications where controlled magnetic behavior or high-density metallic properties are required.
