The magnetization dynamics of nonuniform magnetic structures induce the spin-dependent force acting on the conduction electrons via the s–d coupling. This emergent electric field, the so-called spin-motive force (SMF), is observed in a variety of magnetic structures such as magnetic domain walls, magnetic vortices, and staggered ferrimagnetic structures. The magnitude and direction of the SMF depend on the spatiotemporal derivative of magnetic structures, which is determined by the magnetic interaction and geometry of the sample. In this article, we review recent studies on the SMF using ferromagnetic and ferrimagnetic materials. We introduce the theoretical aspect of the SMF and show the relationship between the SMF and the topology of the magnetic structure. We present the experiment on the SMF induced by various magnetic samples in the presence of ferromagnetic coupling, the dipole–dipole interaction, and the antiferromagnetic coupling.

铁磁和亚铁磁材料中的自旋动力

非均匀磁性结构的磁化动力学通过 s-d 耦合感应作用在传导电子上的自旋相关力。这种出现的电场，即所谓的自旋动力 (SMF)，可以在各种磁结构中观察到，例如磁畴壁、磁涡和交错亚铁磁结构。SMF 的大小和方向取决于磁结构的时空导数，这是由样品的磁相互作用和几何形状决定的。在本文中，我们回顾了最近对使用铁磁和亚铁磁材料的 SMF 的研究。我们介绍了 SMF 的理论方面，并展示了 SMF 与磁结构拓扑之间的关系。
