· JVASP-19928· TmCu

TmCu is an intermetallic compound combining thulium (a rare-earth element) with copper, belonging to the family of rare-earth–transition metal intermetallics. This material is primarily of research interest rather than established industrial production, studied for its potential in high-performance applications where the combination of rare-earth and transition-metal properties—such as magnetic responsiveness, thermal stability, or specialized electronic behavior—may offer advantages over conventional alloys.
