· SmNi2B2C

SmNi₂B₂C is a quaternary intermetallic compound combining samarium (a rare-earth element) with nickel, boron, and carbon. This material belongs to the family of rare-earth nickel borocarbides, which are primarily investigated in research contexts for their superconducting and other advanced physical properties at low temperatures. The material is not widely used in conventional industrial applications but represents an active area of materials research, particularly for understanding the electronic structure and potential cryogenic performance of rare-earth-based intermetallics.
