· SmAu

SmAu is an intermetallic compound formed between samarium (a rare earth element) and gold, belonging to the class of rare earth–noble metal intermetallics. This material combines the unique electronic and magnetic properties of samarium with gold's chemical stability and corrosion resistance, making it of primary interest in research contexts rather than high-volume industrial production. SmAu and related rare earth–gold phases are explored for specialized applications requiring controlled magnetic behavior, high-temperature stability, or specific electronic properties.
