论文摘要
在这项工作中，我们描述了操纵Bloch壁类型局部配置的内部结构的过程。我们考虑一个三场模型，并基于静态场能量的最小化发展一阶形式主义。结果表明，第三场可以被解耦，并用于改变Bloch壁的几何布置，从而产生其内部结构的多种修饰。该过程捕获了超出标准情况的效果，并且可以用于几种实际感兴趣的应用，特别是用于研究纳米尺度上磁性材料的磁化。
In this work, we describe a procedure to manipulate the internal structure of localized configurations of the Bloch wall type. We consider a three-field model and develop a first order formalism based on the minimization of the energy of the static fields. The results show that the third field may be decoupled and used to change the geometric arrangement of the Bloch wall, giving rise to a diversity of modifications of its internal structure. The procedure captures effects that goes beyond the standard situation and can be used in several applications of practical interest, in particular, for the study of the magnetization of magnetic materials at the nanometric scale.
