SmBiAu2
metal· JVASP-39074· SmBiAu2
SmBiAu2 is an intermetallic compound combining samarium (rare earth), bismuth, and gold in a 1:1:2 stoichiometry. This is a research-phase material primarily investigated for its potential in thermoelectric and electronic applications where rare earth intermetallics offer tailored electronic band structures and phonon scattering properties. The material's high density and mixed-valence character make it of interest in condensed matter physics and materials research, though it has not yet reached widespread industrial adoption; similar rare earth bismuth-gold phases are being explored as candidates for mid-range thermoelectric conversion and magnetoelectronic devices.
