Abstract
Effects of crystallization and nitrogenation on permanent magnetic properties have been investigated in the Sm2Fe17 alloy. It has been shown that the high nitrogen gas pressure of several 100kgf/cm2 is effective for nitrogenation of Sm2Fe17 powder which has an appropriate particle size. The nitrogenated compound Sm2Fe17Nx, under condition of several 100kgf/cm2 in N2 atmosphere has a saturation magnetization of 145emu/g. This value is smaller than that of literature one (160emu/gr) because of impurities of O2 and Fe.
