Sm5Co2
metal· JVASP-21475· Sm5Co2
Sm₅Co₂ is an intermetallic compound combining samarium (a rare-earth element) with cobalt, belonging to the family of rare-earth transition-metal alloys. This material is primarily of research and specialized industrial interest, valued for its potential in high-temperature applications and magnetic systems where the rare-earth component can contribute to magnetic performance. The samarium-cobalt system has been explored historically for permanent magnet development and high-temperature structural applications, though Sm₅Co₂ specifically remains a niche composition compared to more common SmCo₅ and Sm₂Co₁₇ variants used in commercial permanent magnets.
