It would be desirable if the magnetic properties of Sm–Fe alloys could be increased without the need for nitrogenation. In this experiment, Sm–Fe bulk magnets were prepared from the Sm–Fe powders by the spark plasma sintering (SPS) technique without nitrogenation. The structures and magnetic properties of the Sm–Fe bulk magnets prepared by the SPS technique were investigated. By optimization of the composition and production process, it was found that the (Sm0.7Zr0.3)(Fe0.7Co0.3)9Ti magnet with the fine Th2Zn17-type phase showed a high coercivity of 4.35 kOe.
