· HoNi5

HoNi5 is an intermetallic compound composed of holmium and nickel, belonging to the rare-earth transition metal alloy family. This material is primarily investigated for magnetic and high-temperature applications due to the unique properties imparted by holmium's rare-earth character combined with nickel's stability. It serves niche roles in specialized research and development contexts, particularly in magnetic devices, permanent magnet systems, and high-performance alloys where rare-earth strengthening is valued.
