Pr11Co89

Pr11Co89 is a rare-earth–cobalt intermetallic compound belonging to the family of permanent magnet materials, where praseodymium provides magnetic hardness and cobalt enhances saturation magnetization and thermal stability. This material is primarily explored in high-temperature magnetic applications and specialized permanent magnet systems, particularly where cobalt-rich rare-earth magnets are engineered for enhanced coercivity and Curie temperature compared to standard NdFeB magnets; it represents a research-focused composition rather than a widely commercialized alloy, making it of interest for advanced aerospace, automotive, and energy applications requiring magnets that maintain performance at elevated temperatures.
