HoNi2B2C

HoNi₂B₂C is a quaternary intermetallic compound combining holmium (rare earth), nickel, boron, and carbon—a material primarily of research interest rather than established industrial production. This compound belongs to the family of rare-earth borocarbides, which have been studied for their potential superconducting and hard-magnetic properties at cryogenic temperatures. While not yet deployed in high-volume commercial applications, materials in this class are explored for specialized roles requiring extreme property combinations, such as high-field magnet systems and potentially cryogenic structural components where conventional alloys prove inadequate.
