Mixed-valance manganites with strong electron correlation exhibit strong potential for spintronics, where emergent magnetic behaviors, such as propagation of high-frequency spin waves and giant topological Hall Effects can be driven by their mesoscale spin textures. Here, we create magnetic vortex clusters with flux closure spin configurations in single-crystal La_0.67Sr_0.33MnO₃ wire. A distinctive transformation from out-of-plane domains to a vortex state is directly visualized using magnetic force microscopy at 4 K in wires when the width is below 1.0 μm. The phase-field modeling indicates that the inhomogeneous strain, accompanying with shape anisotropy, plays a key role for stabilizing the flux-closure spin structure. This work offers a new perspective for understanding and manipulating the non-trivial spin textures in strongly correlated systems.

具有强电子相关性的混合价亚锰酸盐表现出强大的自旋电子学潜力，其中出现的磁行为，例如高频自旋波的传播和巨大的拓扑霍尔效应可以由它们的中尺度自旋纹理驱动。在这里，我们在单晶 La _0.67 Sr _0.33 MnO _{3中创建了具有通量闭合自旋配置的磁涡旋簇}金属丝。当宽度低于 1.0 μm 时，使用 4 K 的磁力显微镜可以直接观察到从面外域到涡流状态的独特转变。相场建模表明，伴随形状各向异性的非均匀应变对于稳定通量闭合自旋结构起着关键作用。这项工作为理解和操纵强相关系统中的非平凡自旋纹理提供了新的视角。
