· JVASP-35287· YbNi4Au

YbNi4Au is a ternary intermetallic compound combining ytterbium, nickel, and gold—a research-phase material that belongs to the broader family of rare-earth metal alloys. This compound is primarily of scientific and academic interest rather than established industrial use, with potential applications in magnetism, thermal management, or specialized functional alloys where the unique electronic properties of ytterbium combined with noble-metal stability could be exploited. Engineers considering this material should treat it as an experimental candidate for niche high-performance applications requiring rare-earth–transition-metal synergy, not as an off-the-shelf engineering material.
