论文摘要
寻找新方法来增强反铁磁（AFM）在运动过程中的稳定性是AFM Spintronic设备的重要问题。在此，基于该模型的Landau Lifshitz Gilbert模拟，对扭曲的AFM Skyrmion的自旋极化电流诱导的动力学进行了数值研究。证明DM相互作用各向异性诱导了天际变形，从而抑制了运动过程中的失真并增强了天际的稳定性。此外，详细研究了DM相互作用各向异性对天际速度的影响，并通过Thiele理论进一步解释了模拟结果。这项工作揭示了一种有希望的策略，以增强AFM Skyrmion的稳定性和最大速度，从而使未来的Spintronic应用受益。
Searching for new methods to enhance the stability of antiferromagnetic (AFM) skyrmion during its motion is an important issue for AFM spintronic devices. Herein, the spin polarized current-induced dynamics of a distorted AFM skyrmion is numerically studied, based on the Landau Lifshitz Gilbert simulations of the model with an anisotropic Dzyaloshinskii Moriya (DM) interaction. It is demonstrated that the DM interaction anisotropy induces the skyrmion deformation, which suppresses the distortion during the motion and enhances the stability of the skyrmion. Moreover, the effect of the DM interaction anisotropy on the skyrmion velocity is investigated in detail, and the simulated results are further explained by Thiele theory. This work unveils a promising strategy to enhance the stability and the maximum velocity of AFM skyrmion, benefiting future spintronic applications.
