metal

· JVASP-18917· TmCo2

TmCo₂ is an intermetallic compound composed of thulium and cobalt, belonging to the rare-earth transition metal intermetallic family. This material is primarily of research and specialized industrial interest, valued for its magnetic properties and potential high-temperature performance characteristics inherent to rare-earth cobalt systems. TmCo₂ and related RCo₅ and R₂Co₇ intermetallics are investigated for permanent magnet applications and magnetocaloric effects, offering alternatives to conventional rare-earth magnets in niche applications where specific thermal, magnetic, or structural properties align with system constraints.
