As well known that if a compression is applied along rolling direction, then the domain magnetized along [001] would be energetically unfavourable. In that case the transverse domains magnetized along [100] or [010] are energetically favourable. So the latter would grow by the wall moving of the nuclei of transverse domains and become the main domain structure. As for the former main domain structure, then it would be degenerated into supplementary. Such stripe like pattern, which is parallel to [110], is so called transverse stripe pattern. With further increase of compression, these transverse stripe pattern would be broken into two groups of differently aligned tilting domain fragments, gradually. There are some correlations between the alignment of these tilting domain fragments and the crystallographic orientations. These two groups of tilting domain fragments intertwine with each other in rows and they are looked ike "λ". The higher the compression, the greater the volume fraction of "λ" domains. The row width and the space of domain fragment itself are also reduced with increase of compression. The cause of formation of such domains is discussed in the light of energy consideration. A model of "λ" domain structure is proposed in the present work.ě 收稿日期: 1983-03-18      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 罗阳 王振琴 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I3/23 1 Moses, A.
