1 Fig. 3 FM MnBi2Te4 bulk. FM MnBi2Te4 bulk. Crystal structure (A) and band structure (B) of the FM bulk. (C) Zoom-in band structures along the out-of-plane Γ-Z and nearly in-plane F-W-L directions. There is a pair of Weyl points at W and W′ = −W. (D) Motion of the sum of WCCs on a small sphere centered at W in momentum space. (E) Surface states of the (11¯0) termination on the isoenergy plane of the Weyl points, demonstrating the existence of Fermi arcs. Jiaheng Li et al.
