Sm4 Fe4 B16

Sm₄Fe₄B₁₆ is a rare-earth iron boride intermetallic compound belonging to the samarium-iron-boron material family, which is primarily explored in permanent magnet and advanced functional material research. This composition sits within the broader context of rare-earth magnetic alloys, though it represents a less common stoichiometry compared to commercial Nd-Fe-B or Sm-Co magnets. The material is of primary interest in materials science research for investigating magnetic properties and phase stability in rare-earth systems, with potential applications in high-temperature magnetic devices or specialty permanent magnet applications where samarium's thermal stability is advantageous over neodymium-based alternatives.
