Schematic show of Weyl points in the whole BZ and Fermi arcs on (001) and (111) surface with magnetization S along [001] direction (a) and [111] direction (b). Red circle and blue dot represent the Weyl points carrying + and — Chern number. Panels (c)–(h) are the Fermi arcs directly calculated based on realistic TB model based the previous experimental parameters. Panels (c), (e), (g) and panels (d), (f), (h) are the results for magnetization S along [001] direction and [111] direction.
