论文摘要
我们报告了在候选磁性Weyl半分刀口中发现拓扑磁性的。使用中子散射，我们发现该系统托管了几个不合格的，正方协调的多 - $ \ vec {k} $磁性阶段，低于$ t _ {\ rm {n}} $。通过观察拓扑厅效应，建议在与$ c $轴平行的中间磁场处相位稳定的拓扑特性。我们的发现重点介绍了一个特殊系统，用于利用实际空间中磁化的非平凡拓扑与动量空间中的Weyl节点之间的相互作用。
We report the discovery of topological magnetism in the candidate magnetic Weyl semimetal CeAlGe. Using neutron scattering we find this system to host several incommensurate, square-coordinated multi-$\vec{k}$ magnetic phases below $T_{\rm{N}}$. The topological properties of a phase stable at intermediate magnetic fields parallel to the $c$-axis are suggested by observation of a topological Hall effect. Our findings highlight CeAlGe as an exceptional system for exploiting the interplay between the nontrivial topologies of the magnetization in real space and Weyl nodes in momentum space.
