本研究提出统一框架，通过解析理论和微磁模拟揭示螺旋度可连续调控拓扑磁纹理的霍尔角，实现高效可编程输运。
AI 中文摘要
拓扑磁纹理可以作为由自旋电流驱动的信息载体。然而，它们的运动通常伴随着霍尔效应，使其偏离电流方向，限制了输运效率和可控性。我们开发了一个统一的实空间变换框架，能够系统研究具有不同螺旋度的混合自旋纹理，如斯格明子、反斯格明子、双子（bimerons）和反双子（antibimerons）。结合解析理论与微磁模拟，我们建立了螺旋度与电流驱动输运之间的关系。广义Thiele方程的解析解将螺旋度识别为几何控制参数，并给出了霍尔角的简单表达式，使其能够连续调谐、完全抑制以及沿任意面内方向确定性操控。微磁模拟证实，在Landau–Lifshitz–Gilbert动力学下产生的自旋纹理保持稳定，并验证了解析预测。这些结果确立了螺旋度作为可编程拓扑磁纹理输运的多功能控制参数。
英文摘要
Topological magnetic textures can serve as information carriers driven by spin currents. However, their motion is generally accompanied by a Hall effect that deflects them from the current direction, limiting transport efficiency and controllability. We develop a unified spin-space transformation framework enabling a systematic study of hybrid spin textures with different helicities, such as skyrmions, antiskyrmions, bimerons, and antibimerons. Combining analytical theory with micromagnetic simulations, we establish the relation between helicity and current-driven transport. An analytical solution of the generalized Thiele equation identifies helicity as a geometric control parameter and yields a simple expression for the Hall angle, enabling its continuous tuning, complete suppression, and deterministic steering along arbitrary in-plane directions. Micromagnetic simulations confirm that the generated spin textures remain stable under Landau--Lifshitz--Gilbert dynamics and validate the analytical predictions. These results establish helicity as a versatile control parameter for programmable transport of topological magnetic textures.
