AI 中文摘要
横向磁性界面为测试斯格明子（skyrmions）在跨越材料参数和磁序的突变时是否保持鲁棒性提供了直接途径。本文采用微磁模拟和解析简化坐标判据，研究斯格明子在平面铁磁体-铁磁体（FM-FM）、反铁磁体-反铁磁体（AFM-AFM）、铁磁体-反铁磁体（FM-AFM）和反铁磁体-铁磁体（AFM-FM）界面的传输情况。根据接收区域形成的形貌，将结果整理为相图，区分出紧凑传输、变形斯格明子、条状畴态、非晶态纹理以及弛豫到背景的情况。同序FM-FM和AFM-AFM的斯格明子传输可通过解析定义的简化 Dzyaloshinskii-Moriya 相互作用范围来描述，该范围确定了支持紧凑传输且无条状形成的壁软化区域。混合序FM-AFM和AFM-FM界面具有方向依赖性，需要在铁磁磁化强度和反铁磁奈尔纹理之间进行转换。这些结果表明，平面界面可作为主动传输元件，并为异质斯格明子轨道提供简化的设计判据。
英文摘要
Lateral magnetic interfaces provide a direct way to test whether skyrmions remain robust when driven across abrupt changes in material parameters and magnetic order. Here we study skyrmion transmission across planar ferromagnet-ferromagnet (FM-FM), antiferromagnet-antiferromagnet (AFM-AFM), ferromagnet-antiferromagnet (FM-AFM), and antiferromagnet-ferromagnet (AFM-FM) interfaces using micromagnetic simulations and analytic reduced-coordinate criteria. The outcomes are organized into phase diagrams according to the morphology formed in the receiving region, distinguishing compact transmission from deformed skyrmions, stripe-domain states, amorphous textures, and relaxation into the background. Same-order FM-FM and AFM-AFM skyrmion transmission is captured by an analytically defined range of the reduced Dzyaloshinskii-Moriya interaction, identifying the wall-softening regime that supports compact transmission without stripe formation. Mixed-order FM-AFM and AFM-FM interfaces are directionally distinct, requiring conversion between ferromagnetic magnetization and antiferromagnetic Néel textures. These results show that planar interfaces act as active transport elements and provide reduced design criteria for heterogeneous skyrmion tracks.
