Quantum Anomalous Hall Effects Controlled by Chiral Domain Walls

We report the interplay between two different topological phases in condensed matter physics, magnetic chiral domain wall (DW), and quantum anomalous Hall (QAH) effect. show that DW driven by Dzyaloshinskii-Moriya interaction (DMI) can divide uniform into several zones where neighboring zone possesses opposite quantized conductance. The separated with a edge state (CES) be continuously modified external field-induced expansion thermal fluctuation, which gives rise to reconfigurable QAH More interestingly, we position of CES tuned spin current-driven motion. Several two-dimensional magnets high Curie temperatures large band gaps are proposed for realizing these phenomena. Our work thus reveals possibility controllable effects.
