Figure 1 (IMAGE) Peking University Caption (a) Schematic crystal structure of MnBi2Te4. The red and blue arrows denote magnetic moments of Mn atoms. (b) High-Chern-number (C=2) Chern insulator state in 10-SL MnBi2Te4 device. (c), (d) Temperature evolution of the high-Chern-number (C=2) Chern insulator state. (e) Schematic C=2 Chern insulator state with two dissipationless edge states. The two different colors are used to distinguish the adjacent MnBi2Te4 SLs.
