摘要： Magnetic material of the Sm-Fe-N system exhibits a crystalline hard magnetic phase with a Th.sub.2 Zn.sub.17 crystalline structure wherein N atoms are incorporated in the crystalline lattice. A preliminary product having a dual component Sm.sub.2 Fe.sub.17 phase is produced by mechanical alloying followed by thermal treatment to achieve the desired microstructure. The preliminary product is heated in a nitrous atmosphere, as a result of which, the hard magnetic phase is formed. The preliminary product may also be obtained by a rapid-quenching technique.
