本章介绍了拓扑和磁畴壁之间的各种联系。首先，我们揭示了拓扑学告诉我们的关于磁畴壁的信息，回答了这样的问题：域壁可能是拓扑缺陷吗？是否存在不同类别的拓扑域壁？然后我们转向动力学，解释拓扑学和磁织构动力学之间的深刻联系，这里是磁场壁。实验方面将在接下来的章节中被回顾，根据材料和样品类型来构建，其中气泡石榴石薄膜扮演着特殊的角色，其中介绍了一些基本概念。作者试图为这个主题的大量文献提供一个统一的观点，这些文献跨越了40年，涉及不同的研究主题。
This chapter presents the various connections between topology and magnetic domain walls. To begin with, we expose what topology tells us about magnetic domain walls, answering questions like: may domain walls be topological defects?, are there topologically different classes of domain walls? We then turn to dynamics, explaining the profound link between topology and the dynamics of magnetic textures, domain walls here. Experimental aspects are reviewed in the next sections, constructed according to material and sample types, with a special role played by bubble garnet films where a number of fundamental concepts were introduced. The authors try to provide a unified view of the vast literature on the subject, that spreads over four decades and different research thematics.
