· JVASP-4355· SmFe5

SmFe5 is an intermetallic compound composed of samarium and iron, belonging to the rare-earth iron family of magnetic materials. It is used primarily in permanent magnet applications where high magnetic strength and thermal stability are required, particularly in electric motors, generators, and magnetic devices operating at elevated temperatures. SmFe5 offers a cost-effective alternative to some higher-performance rare-earth magnets while retaining strong ferrimagnetic properties, making it relevant for applications where performance-to-cost balance is critical.
