· JVASP-9735· TbCuS2

TbCuS2 is an intermetallic compound combining terbium (a rare-earth element), copper, and sulfur in a ternary system. This material belongs to the family of rare-earth transition-metal chalcogenides and is primarily studied in research contexts for its electronic and magnetic properties rather than established commercial applications. Engineers and materials scientists investigate such compounds for potential use in semiconducting devices, magnetic applications, and advanced functional materials where rare-earth elements provide unique electronic or magnetic behavior.
