· JVASP-22354· Ho2NiAs2

Ho₂NiAs₂ is an intermetallic compound containing holmium, nickel, and arsenic, belonging to the class of ternary metal arsenides. This material is primarily of research interest rather than established in mainstream engineering applications, studied for its magnetic and electronic properties that arise from the rare-earth holmium content combined with transition metal nickel.
