Preparation and magnetic property of Sm2Fe17Nx fine powders sorbed by zinc vapor

摘要

Finely ground powders of Sm2Fe17Nx were uniformly sorbed with the Zn vapor formed at 623-673 K in evacuated glass tubings, so that coercivity (H-cj) values and oxidation resistance of the resulting Zn/Sm2Fe17Nx powders were considerably improved to a practical use level as bonded magnet materials compared with those of the untreated powder.
