· SmNi5

SmNi5 is an intermetallic compound composed of samarium and nickel, belonging to the rare-earth intermetallic family. This material is primarily used in permanent magnet applications and hydrogen storage systems, where its stable crystal structure and high saturation magnetization make it valuable for specialized electromagnetic and energy storage devices. SmNi5 is notable for its hydrogen absorption capacity and thermal stability, making it relevant in both legacy magnet technology and emerging clean energy applications, though it has been partially superseded by newer rare-earth compounds in some high-performance markets.
