论文摘要
拉伸应变是通过可调磁各向异性和dzyaloshinskii-Moriya相互作用的可调节控制在手性Helimagnets中创建和操纵磁性词素纹理的有前途的工具。在这里，通过使用原位谐振小角度X射线散射，我们证明了Skyrmion和手性孤子晶格可以作为Fege Lamella中的亚稳态达到fege Lamella中的可稳态状态，作为不同的状态，甚至通过在各种方向与相对于变形的各种方向相结合，从而同时将其作为不同的状态。分析模型框架中讨论了小角度散射数据，该数据足以描述孤子晶格的实验结果。通过使用实验结果和分析理论，通过微磁模拟分析了小角度散射实验所见的垂直磁场中亚稳态的垂直磁场中的放松。
The tensile strain is a promising tool for creation and manipulation of magnetic solitonic textures in the chiral helimagnets via tunable control of magnetic anisotropy and Dzyaloshinskii-Moriya interaction. Here, by using the in-situ resonant small-angle x-ray scattering we demonstrate that the skyrmion and chiral soliton lattices can be achieved as metastable states in FeGe lamella as distinct states or even simultaneously by combining the tensile strain and magnetic fields in various orientations with respect to the deformation. The small-angle scattering data are discussed in the frame of the analytical model which is sufficient to describe the experimental results for soliton lattice. By using the experimental results and analytical theory, unwinding of the metastable skyrmions in the perpendicular magnetic field as seen by small-angle scattering experiment was analyzed by the micromagnetic simulation.
