Аннотация:In this paper, we report on the structure and magnetic properties of the (Sm,Er)-Fe-(N,H) samples and nitrided powders prepared by high-energy ball milling. Sm1.8Er0.2Fe17N2 and Sm1.8Er0.2Fe17H4.6 have a Th2Zn17-type of structure as the parent compound. Analysis of milled powders’ particle size indicated that the increasing milling time promotes agglomerates’ appearance. The magnetic study showed that ball-milling processing increases the coercivity of the materials: highest value was found for the Sm1.2Er0.8Fe17N2 powder subjected to grinding for 60 minutes. The observed regularities in the magnetic properties formation of (Sm,Er)-Fe-N are essential for preparation hard magnetic materials.
