SmFeP

metal

· JVASP-37278· SmFeP

SmFeP is an intermetallic compound composed of samarium, iron, and phosphorus, belonging to the rare-earth metal family. This material is primarily of research interest for applications requiring magnetic properties or high-temperature stability, as rare-earth iron phosphides exhibit potential in permanent magnets, magnetocaloric devices, and advanced functional materials. SmFeP represents an experimental composition within the broader class of rare-earth intermetallics, which are actively investigated for next-generation energy conversion and magnetic applications where conventional ferromagnets are insufficient.
