metal

· JVASP-14272· YbAu4

YbAu₄ is an intermetallic compound composed of ytterbium and gold, belonging to the class of rare-earth metal intermetallics. This material is primarily studied in condensed matter physics and materials research rather than as an established engineering alloy, with potential applications in low-temperature physics, Kondo systems research, and specialized electronic devices where rare-earth-gold compounds exhibit unusual electronic and magnetic properties.
