HoAu4 is an intermetallic compound composed of holmium and gold, representing a rare-earth/noble-metal system of primary research interest rather than established industrial production. This material belongs to the family of gold-based intermetallics, which are studied for specialized applications requiring the unique combination of gold's chemical inertness with rare-earth elements' magnetic and electronic properties. While not widely deployed in conventional engineering, HoAu4 and similar rare-earth gold compounds are investigated in academic and specialized industrial contexts for high-performance applications where precious-metal stability and rare-earth functionality intersect.
