Abstract

The regularities of the formation of the magnetic structure near the systems of Bloch–Néel domain walls realized in the presence of an external magnetic field have been studied using the example of thin Fe_0.25Ni_0.75 films. It has been established that when the film is magnetized along the easy axis (EA), a stable quasi-closed distribution of magnetization (a blocked domain structure) is formed near the approaching domain walls. Under the action of a field oriented perpendicular to the EA, the blocked domain structure is transformed into a system of localized domains. A model that substantiates the observed transition is proposed.

摘要

以Fe _0.25 Ni _0.75薄膜为例，研究了在存在外部磁场的情况下在Bloch-Néel畴壁系统附近形成的磁性结构的规律。已经确定，当沿易轴（EA）磁化薄膜时，在接近的畴壁附近会形成稳定的准闭合磁化分布（受阻畴结构）。在垂直于EA定向的场的作用下，受阻域结构被转换为局部域系统。提出了证实观察到的过渡的模型。
