摘要
研究了Ｃｒ部分取代Ｆｅ对Ｓｍ２（Ｆｅ１－ｘＣｒｘ）１７Ｎ～２．７磁粉磁特性的影响。添加少量Ｃｒ（ｘ＝０－０．１），该化合物的结构不变化。随Ｃｅ含量的增加，它的Ｃｕｒｉｅ温度、各向异性场饱和磁化强度、平均Ｆｅ原子磁矩和平均超精细场均有所降低。材料的单相性显著改善，矫顽力提高。Ｓｍ２（Ｆｅ０．９５Ｃｒ０．０５）１７Ｎ～２．７磁粉的矫顽力ｉＨｃ达到１５９２ｋＡ／ｍ。
Effect of Cr in substitution for a part of Fe on structure and magnetic properties of Sm_2(Fe_(1-x)Cr_x)_(17)N_(~2.7) alloys powder has been investigated.The structure of the alloys remains the same with an addition of Cr,saying x=0-0.1.With the increase of Cr content,their Curie temperature,anisotropic field.saturation magnetization,average Fe atom moment and average hyperfine field decrease slightly.But their homogeneity may be obviously improved and coercivity increased even up to 1592 kA/m for Sm_2(Fe_0.95Cr_0.05)_17N_(~2.7) powder.
