Sm2Fe17N
metal· JVASP-133415· Sm2Fe17N
Sm₂Fe₁₇N is a rare-earth iron nitride compound belonging to the family of permanent magnetic materials, specifically developed for high-performance magnet applications. This material is notable in permanent magnet technology because it offers improved magnetic properties and thermal stability compared to conventional ferrite magnets, though it remains primarily in research and specialized industrial development phases. Engineers select this composition for applications requiring strong permanent magnetism in compact form factors, particularly where enhanced performance over traditional iron-based magnets justifies material and processing complexity.
