用穆斯堡尔谱学方法研究了SmCo3.66Fe0.13Sn0.06烧结薄片的119Sn谱。发现Sn处磁分裂约为零。得出了Sn近邻区域处于顺磁状态中,添加的大部分Sn及Fe,Sn原子比不小于1:2的Fe均匀地进入了SmCo5晶格,Fe在Sn近邻形成了主要特征组份相近于FeSn2的有序排列结构的结论。讨论了这一组态及与之相联系的可能呈现的自旋排布对矫顽力的影响。The 119Sn M?ssbauer spectra of SmCo3.66Fe0.13Sn0.06 PM sintering slices have been studied by M?ssbauer spectoscopy. At tin nuclei, near zero magnetic splitting was observed. It was concluded that the majority of additive tin and iron whose atomic ratio is not less than 2:1 entered into the lattice of SmCo5 homogeneously and the iron-tin neighbour developed an ordered structure. The principal characteristic constituents is similar to FeSn2. The effect of coercive force of these atomic configuration and possibly emerging spin configuration is discussed.
