Er2Fe14B
metal· Er2Fe14B
Er2Fe14B is an intermetallic compound in the rare-earth iron boride family, structurally related to the Nd2Fe14B permanent magnet but with erbium substituted for neodymium. This material is primarily of research and development interest rather than established production use, being investigated for high-temperature permanent magnet applications where superior thermal stability compared to standard neodymium magnets is desired. The erbium addition provides potential improvements in coercivity and Curie temperature, making it notable for applications requiring magnets to operate reliably at elevated temperatures where conventional rare-earth magnets would lose magnetization.
