Sm3AlFeS7
metal· JVASP-147278· Sm3AlFeS7
Sm₃AlFeS₇ is an intermetallic compound combining samarium (a rare-earth element), aluminum, iron, and sulfur in a ternary sulfide system. This is a research-phase material primarily studied in solid-state chemistry and materials science contexts rather than established industrial production. The compound represents exploration into rare-earth-containing sulfides for potential applications in thermoelectric devices, solid-state electronics, and specialized magnetic materials, though it remains largely confined to laboratory investigation rather than widespread engineering use.
