Аннотация: The composition, structure, and surface topology of as-cast, homogenized, and nitrogenized alloybased on an intermetallic compound Sm2Fe17 with partial substitution of samarium atoms with holmiumatoms have been studied using X-ray fluorescence and X-ray phase analysis, as well as scanning electronmicroscopy. Results on the magnetic properties of the initial compound Sm1.2Ho0.8Fe17 and the nitrideSm1.2Но0.8Fe17N2.4 and its milled powders have been presented. It has been found that partial substitution ofsamarium atoms with holmium ones in a rare-earth metal sublattice in combination with the effect of introducing nitrogen atoms into the initial compound crystal lattice increases such magnetic characteristics as specific magnetization and coercive force. A comparative analysis of the magnetic hysteresis properties of powdersamples showed that increasing the duration of the milling of the Sm–Ho–Fe–N powders using high-energyball milling (15, 30, 45, and 60 min) contributes to improving the main magnetic characteristics. Functionalcharacteristics obtained for Sm–Ho–Fe–N powders after their milling are important for the development ofnew high-coercivity magnets based on them.
