磁织构可以通过电流通过自旋转移和自旋-轨道-力矩机制来操纵。我们回顾如何利用这些扭矩可以创建手征的磁性纹理与打破反转对称性的磁铁，包括畴壁和skyrmions。这些手性纹理也可以通过（电）电流移动，并遵循非常丰富的动力学。例如，磁畴壁具有著名的步行者击穿，而磁旋则受到斯基尔米恩霍尔效应的影响，这是植根于它们的真实空间拓扑结构。这些性质导致了各种潜在的新的应用，我们简要概述。
Magnetic textures can be manipulated by electric currents via the mechanisms of spin-transfer and spin-orbit-torques. We review how these torques can be exploited to create chiral magnetic textures in magnets with broken inversion symmetries, including domain walls and skyrmions. These chiral textures can also be moved by (electric) currents and obey very rich dynamics. For example, magnetic domain walls feature the famous Walker breakdown, and magnetic whirls are subject to the skyrmion Hall effect, which is rooted in their real-space topology. These properties led to a variety of potential novel applications which we briefly overview.
