SmErFe4
metal· JVASP-107526· SmErFe4
SmErFe4 is an intermetallic compound combining samarium, erbium, and iron elements, belonging to the rare-earth iron family of materials. This composition is primarily of research and development interest rather than established industrial production, with potential applications in permanent magnet systems and high-temperature magnetic devices where the rare-earth iron backbone offers enhanced magnetic performance. The specific SmErFe4 stoichiometry represents an experimental formulation within the broader rare-earth ferromagnetic alloy family, studied for optimizing magnetic anisotropy and thermal stability in specialized applications.
