Abstract
Sm2Fe17N3 magnets were prepared by Zn-bonding of coarse grained powder , additional milling after nitrogenation, or grain refinement of Sm2Fe 17 by HDDR. They exhibit significant differences in microstructure and magnetization behaviour, but show common differences to sintered Nd-F e-B, possibly due to the presence of very small particles. During long milling, Sm2Fe17N3 powders become exchange coupled two phase material s.
