General characteristics of nanostructured permanent magnet materials is presented. The experimental data for Sm2Fe17N3 type magnets are shown. The materials were prepared by mechanical alloying, diffusion annealing and nitriding. The magnetic properties are discussed in the light of the processing parameters and material composition. The effect of nanostructure on the magnetic properties and Curie temperature has been proved. The influence of Co and Ga addition is also mentioned. Consolidation methods of nanocrystalline powders are proposed.
