Dzyaloshinskii畴壁的非互易弯曲动力学
Nonreciprocal flexural dynamics of Dzyaloshinskii domain walls
摘要：
我们重新审视铁磁畴壁动力学的描述，通过一个扩展的一维模型，允许弯曲变形的墙壁在其运动。考虑到这一点，允许畴壁中心和内角是平行于畴壁方向上位置的函数。在小外加场的限制下，该模型考虑了壁模传播的非互易性及其在Dzyaloshinskiii-Moriya相互作用和面内磁场存在下的稳定性。
英文摘要：
We revisit the description of ferromagnetic domain wall dynamics through an extended one-dimensional model by allowing flexural distortions of the wall during its motion. This is taken into account by allowing the domain wall center and internal angle to be functions of position in the direction parallel to the wall. In the limit of small applied fields, this model accounts for the nonreciprocity in the propagation of wall modes and their stability in the presence of the Dzyaloshinskii-Moriya interaction and in-plane magnetic field.
