Achieving a very strong magnetic anisotropy in a 3d material is a difficult, but not an impossible task. It is difficult because there is no general recipe (necessary condition) for a strong anisotropy in a band magnet. Several strategies can be pursued in this situation. One of them is to re-examine the less studied 3d compounds, somewhat neglected since the discovery of the Nd-Fe-B magnets 30 years ago. As an example, a single crystal of (Fe0.7Co0.3)2B has been investigated in this work.
在一种三维材料中实现非常强的磁各向异性是一项困难但并非不可能完成的任务。之所以困难，是因为对于能带磁体中的强各向异性不存在通用的方法（必要条件）。在这种情况下可以采用几种策略。其中之一是重新审视那些研究较少的三维化合物，自30年前发现钕铁硼磁体以来，它们在一定程度上被忽视了。例如，在这项工作中对(Fe0.7Co0.3)2B单晶进行了研究。
