In order to investigate the effect of the replacement of Fe atoms by Ni atoms on the magnetic properties of such compounds, easy directions of magnetization were determined by X-rays for different Ni contents, and the dependence of the saturation magnetization in a magnetic field up to 70,000 Oe on x values of the compounds was also studied. Mossbauer spectra of Y_2Fe_(17) and Y_2 (Fe_(0.9)Ni_(0.1))_(17) were taken ~1to ascertain order or disorder distributions of Ni atoms in the crystalline lattices. An explanation of the cause of variation of Curie temperature with the Ni contents of the compounds has been given on the basis of the above results. 收稿日期: 1978-01-18      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 杨应昌 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I1/51 [1] Barbara, B. et al., Int.
