TbCu3S3

TbCu3S3 is an intermetallic compound combining terbium (a rare-earth element) with copper and sulfur, forming a ternary metal sulfide. This material is primarily of research interest rather than established in commercial production, studied for its potential electronic and magnetic properties arising from rare-earth–transition metal interactions. Applications would likely target advanced functional materials where rare-earth magnetism and copper's conductivity can be leveraged, though the compound remains in the experimental phase of materials development.
