YbCu4Au
metal· JVASP-63220· YbCu4Au
YbCu4Au is an intermetallic compound combining ytterbium, copper, and gold, belonging to the family of rare-earth-transition metal alloys. This material is primarily of research interest rather than established industrial production, investigated for its potentially unique electronic and magnetic properties arising from the interplay between rare-earth and noble metal elements. Such ternary intermetallics are studied in fundamental materials science and condensed matter physics to understand electron correlations and crystal structure effects, with potential applications in specialized electronic or magnetic device development.
