We investigated the effect of substitutional elements on magnetic properties of Ni_3 (Mn_<3-x>・M_x)Sn_2 system alloys. The samples were prepared by cast method. The substitutional elements (M) were transition metals Fe and Co, and the x value was set to range from 0 to 1.5. In Fe substituted series, Ni_3 (Mn_<3-x>・M_x)Sn_2, saturation magnetization increased as x value increased, but maximum permeability decreased. Therefore, it was found that the samples of Fe substituted series were unsuitable to soft magnetic materials. However it was also found that the samples of Co substituted series heat treated at 800℃ for 3 hrs, showed that the magnetic properties for soft magnetic materials were improved in the range of 0≦x≦1.0. Especially, it was confirmed that Curie temperature increased monotonically and the magnetostriction decreased as Co content increased.
