摘要

The study of topology in quantum materials has fundamentally advanced theunderstanding in condensed matter physics and potential applications in nextgenerationquantum information technology. Recently, the discovery of a topologicalChern phase in the spin–orbit-coupled Kagome lattice TbMn_6Sn_6 hasattracted considerable interest. Whereas these phenomena highlight the contributionof momentum space Berry curvature and Chern gap on the electronictransport properties, less is known about the intrinsic real space magnetictexture, which is crucial for understanding the electronic properties and furtherexploring the unique quantum behavior. Here, the stabilization of topologicalmagnetic skyrmions in TbMn_6Sn_6 using Lorentz transmission electron microscopynear room temperature, where the spins experience full spin reorientationtransition between the a- and c-axes, is directly observed. An effectivespin Hamiltonian based on the Ginzburg–Landau theory is constructed andmicromagnetic simulation is performed to clarify the critical role of Ruderman–Kittel–Kasuya–Yosida interaction on the stabilization of skyrmion lattice. Theseresults not only uncover nontrivial spin topological texture in TbMn_6Sn_6, butalso provide a solid basis to study its interplay with electronic topology.
