· Co4 Sm10

Co4Sm10 is an intermetallic compound combining cobalt and samarium in a 4:10 stoichiometric ratio, belonging to the rare-earth transition metal intermetallic family. This material is primarily of research and development interest for permanent magnet applications, leveraging samarium's strong magnetic properties combined with cobalt's magnetic and thermal stability. Industrial adoption remains limited, but the material family is explored as an alternative to conventional rare-earth permanent magnets in specialized high-temperature or cost-sensitive applications where samarium-cobalt chemistry offers advantages over neodymium-based systems.
