WebFirst of all, significant EB of the order of ∼200 Oe is induced which means that Fe magnetization forced by the external field to align with its hard axis, imprints the CoO spins orientation parallel to Fe[0 0 1] direction as the system passes its Néel temperature. Importantly, not only impact of ferromagnet on antiferromagnet is observed ... For most magnetically anisotropic materials, there are two easiest directions to magnetize the material, which are a 180° rotation apart. The line parallel to these directions is called the easy axis. In other words, the easy axis is an energetically favorable direction of spontaneous magnetization.
