Ho2Co17
metal· Ho2Co17
Ho₂Co₁₇ is an intermetallic compound in the rare-earth cobalt family, combining holmium with cobalt in a fixed stoichiometric ratio. This material is primarily of research interest for permanent magnet and magnetic device applications, leveraging the strong magnetic properties that arise from holmium's high magnetic moment combined with cobalt's ferromagnetic character. While not widely deployed in high-volume production, intermetallics of this type are investigated for specialized high-performance magnetic systems and high-temperature magnetic applications where conventional permanent magnets reach their limits.
