By examining the ~(57)Fe Mǒssbauer spectra of Co doped specimen, it is observed that Co atoms, while their amount is small, preferentially enter k_2 site of Fe and thus creat unequivalent sites of their nearest neighbors, e. g. k_1 and j_2 Fesites. And they will enter other Fe-site if more Co was doped. 收稿日期: 1987-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王怀玉 曾训一 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/293 1 Sagawa M, Fujimura S, Togawa M et al.
