Abstract

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.
