Abstract Nanocomposite permanent magnet material is the latest generation of permanent magnet material, which is formed by combining a hard magnetic phase with high magnetocrystalline anisotropy and a soft magnetic phase with high saturation magnetization in the nanometer scale. For magnetic materials, the maximum magnetic energy product ((BH)max) is significantly higher than that of NdFeB permanent magnet mate-rials. However, since the nanocomposite permanent magnet material needs to recombine the two phases at the nanometer scale, the preparation process is complicated, and the experimental data is far from the theoretical calculation value. In recent years, many researchers have carried out research on nanocomposite permanent magnet materials, which has greatly improved the production process and magnetic properties of the material. This paper briefly introduces the development history of nanocomposite permanent magnet materials, and focuses on the latest research results on the effects of alloying elements and different heat treatment methods on the magnetic properties of the material, as well as different preparation processes represented by melt quenching. And the future development direction of nanocomposite permanent magnet materials is explored at the same time.
