· JVASP-17379· YbSi2Au2

YbSi2Au2 is an intermetallic compound combining ytterbium, silicon, and gold—a rare-earth-based metallic material belonging to the family of Heusler or similar complex intermetallics. This is primarily a research-phase material studied for its electronic and structural properties rather than an established commercial alloy. The compound is of interest in fundamental materials science for investigating electron behavior in rare-earth systems, and potential future applications in thermoelectric devices, semiconductor interfaces, or specialized electronic components where the unique electronic density of states from ytterbium hybridization may offer advantages.
