a Band structure with the magnetic moment parallel to the a-axis with spin–orbit coupling. The inset shows the Brillion zone of the hexagonal structure. b Intrinsic anomalous Hall conductivity calculated from the Berry curvature from the band structure. c ARPES intensity plot along with the M1–Γ–M4 direction with calculated bands overlaid on top. d ARPES intensity plot along with the M2–M3 direction with calculated bands overlaid on top. e Fermi surface map of MnBi at kz = 0, which represents the photoemission intensity integrated over a small energy window E = EF ± 20 meV around the Fermi level. f Calculated Fermi surface at kz = 0. g Density of states. h Schematic view of the density of states, showing light semi-metallic bands in the spin-up channel and heavy metal bands in the spin-down channel.
