· JVASP-18271· TbInCu2

TbInCu2 is an intermetallic compound combining terbium (a rare-earth element), indium, and copper. This is a research-stage material studied primarily for its potential in magnetocaloric and thermoelectric applications, where the interaction between rare-earth magnetism and metallic electron transport offers tailored functional properties. Industrial adoption remains limited; the material belongs to an emerging class of rare-earth intermetallics being explored to replace or supplement conventional cooling and energy conversion technologies in specialty applications.
