Topological charge Q classifies non-trivial spin textures and determines many of their characteristics. Most abundant are topological textures with |Q| ≤ 1, such as (anti)skyrmions, (anti)merons or (anti)vortices. In this study we created and imaged in real space magnetic skyrmion bundles, that is, multi-Q three-dimensional skyrmionic textures. These textures consist of a circular spin spiral that ties together a discrete number of skyrmion tubes. We observed skyrmion bundles with integer Q values up to 55. We show here that electric currents drive the collective motion of these particle-like textures similar to skyrmions. Bundles with Q ≠ 0 exhibit a skyrmion Hall effect with a Hall angle of ~62°, whereas Q = 0 bundles, the so-called skyrmioniums, propagate collinearly with respect to the current flow, that is, with a skyrmion Hall angle of ~0°. The experimental observation of multi-Q spin textures adds another member to the family of magnetic topological textures, which may serve in future spintronic devices.

拓扑电荷Q对非平凡的自旋纹理进行分类并确定它们的许多特征。最丰富的是拓扑纹理与 | 问| ≤ 1，例如 (anti)skyrmions、(anti)merons 或 (anti)vortices。在这项研究中，我们在真实空间中创建并成像了磁性斯格明子束，即多Q三维斯格明子纹理。这些纹理由一个圆形自旋螺旋组成，该螺旋将离散数量的skyrmion管连接在一起。我们观察到整数Q值高达 55的斯格明子束。我们在这里展示了电流驱动这些类似于斯格明子的类粒子纹理的集体运动。Q ≠ 0 的束 表现出霍尔角约为 62° 的斯格明子霍尔效应，而Q  = 0 束，即所谓的skyrmioniums，相对于电流共线传播，也就是说，skyrmion 霍尔角约为 0°。多Q自旋纹理的实验观察为磁性拓扑纹理家族增加了另一个成员，这可能会在未来的自旋电子器件中发挥作用。
