摘要：

The extensive use of rare earth permanent magnetic materials has led to excessive consumption of low abundance and high cost rare earth elements such as Pr，Nd，Dy and Tb，while the high-abundance rare earth elements La，Ce and Y have not been fully utilized，resulting in a serious imbalance in the utilization of rare earth elements，which is not conducive to the healthy and sustainable development of the utilization of rare earth resources in China. Considering the national strategic security and raw material cost，the research and development of low-cost，high-performance rare earth permanent magnetic materials with high abundance is imperative. In this paper，the research status of high abundance rare earth permanent magnetic materials is summarized，the microstructure characteristics and performance control technologies of Ce rich magnets，La rich，Ce rich magnets and Y rich magnets are introduced respectively，and the development of high abundance rare earth permanent magnetic materials is discussed and prospected. © 2023 Chinese Society of Rare Earths.
