Topologically nontrivial spin textures such as vortices, skyrmions, and monopoles are promising candidates as information carriers for future quantum information science. Their controlled manipulation including creation and annihilation remains an important challenge toward practical applications and further exploration of their emergent phenomena. Here, we report controlled evolution of the helical and skyrmion phases in thin films of multiferroic Te-doped Cu₂OSeO₃ as a function of material thickness, dopant, temperature, and magnetic field using in situ Lorentz phase microscopy. We report two previously unknown phenomena in chiral spin textures in multiferroic Cu₂OSeO₃: anisotropic scaling and channeling with a fixed-Q state. The skyrmion channeling effectively suppresses the recently reported second skyrmion phase formation at low temperature. Our study provides a viable way toward controlled manipulation of skyrmion lattices, envisaging chirality-controlled skyrmion flow circuits and enabling precise measurement of emergent electromagnetic induction and topological Hall effects in skyrmion lattices.

拓扑上无关紧要的自旋纹理（例如涡旋，天旋子和单极子）有望成为未来量子信息科学的信息载体。它们的受控操作（包括创建和an灭）仍然是实际应用和进一步探索其出现现象的重要挑战。在这里，我们使用原位洛伦兹相显微镜报告了多铁性Te掺杂Cu ₂ OSeO ₃薄膜中螺旋相和天空相的受控演化与材料厚度，掺杂剂，温度和磁场的关系。我们报告了多铁性Cu ₂ OSeO ₃中手性自旋织构的两个先前未知的现象：具有固定Q状态的各向异性缩放和通道化。天敌离子通道有效地抑制了最近报道的低温下第二个天敌离子相的形成。我们的研究提供了一种可行的方法来控制天蝎子晶格的可操作性，设想了手性控制的天蝎子流路，并能够精确测量天蝎子晶格中出现的电磁感应和拓扑霍尔效应。
