Sm1 Fe5

Sm₁Fe₅ is an intermetallic compound combining samarium (a rare-earth element) with iron in a 1:5 stoichiometric ratio. This material belongs to the rare-earth iron intermetallic family, which exhibits strong magnetic properties and is primarily investigated for permanent magnet and magnetic device applications. The compound is notable in research contexts for its potential in high-performance magnetic systems where rare-earth permanent magnets are required, though it is less commonly used industrially compared to established rare-earth magnet compositions like NdFeB or SmCo₅.
