SmDyFe17

SmDyFe17 is a rare-earth iron-based intermetallic compound combining samarium and dysprosium with iron in a fixed stoichiometric ratio. This material belongs to the family of rare-earth permanent magnets and hard magnetic phases, engineered to achieve high magnetic coercivity and saturation magnetization through rare-earth substitution. It is primarily investigated for high-temperature magnetic applications where superior thermal stability and coercive strength are required beyond conventional ferrite or alnico magnets, though it remains largely in the research and development phase rather than commodity production.
