SmNi3

metal

· JVASP-126339· SmNi3

SmNi₃ is an intermetallic compound in the rare-earth nickel family, formed from samarium and nickel in a 1:3 stoichiometric ratio. This material is primarily of research and experimental interest, studied for its magnetic and electronic properties rather than established in high-volume industrial production. SmNi₃ belongs to a family of rare-earth intermetallics with potential applications in permanent magnets, magnetocaloric devices, and advanced functional materials where the coupling between rare-earth magnetism and transition-metal electronic structure offers unique performance.
