SmYFe17
metal· JVASP-137675· SmYFe17
SmYFe17 is an intermetallic compound in the rare-earth iron family, combining samarium (Sm) and yttrium (Y) with iron (Fe) in a fixed stoichiometric ratio. This material is primarily of research and development interest for permanent magnet applications, where the rare-earth iron backbone offers potential for high magnetic performance at reduced cost compared to conventional rare-earth magnets. SmYFe17 and related ThMn12-type structure compounds are investigated as alternatives to Nd-Fe-B magnets, particularly where thermal stability, corrosion resistance, or material abundance considerations drive material selection.
