Ho2Au

Ho₂Au is an intermetallic compound combining holmium (a rare earth element) with gold, belonging to the family of rare earth–noble metal intermetallics. This material is primarily of research and specialized interest rather than widespread industrial production, explored for its unique magnetic and electronic properties that arise from the combination of rare earth and precious metal components. Applications remain largely experimental or niche, focused on advanced functional materials where the interplay of magnetic ordering, high density, and thermal stability can be leveraged.
