【摘要】 用穆斯堡尔谱学方法研究了SmCO_3.66Fe_0.13Sn_0.06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。更多还原

【Abstract】 The ¹¹⁹Sn Mossbauer spectra of SmCo3.66 Fe0.13 Sn0.06 PM sintering slices have been studied by Mossbauer spectoscopy.At tin nuclei, near zero magnetic splitting was observed. It was concluded that the majority of additive tin and iron whose ato更多还原
