The patterns show either fairly straight lines or wavy and even more complicated forms. No lace-like pattern has been observed, however. Based on the magnetic properties of the phase and on the effects of orientations and sizes of the crystallites, it has been inferred that the ζ-phase has a domain structure typical of uniaxial ferromagnetics with large magnetic anisotropy but owing to the minute size of the crystallite the domain structure is more or less simplified as no spike-in domains are formed. In the pulverized specimen, regions deposited with magnetic powders can be easily observed and they have been tentatively identified as single domain particles. 收稿日期: 1964-02-18      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 曽训一 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1964/V7/I2/174 [1] Kono.
