a, schematic plot of 2D projected bulk FS based on calculations from Fig. 1c. b, 3D bulk FS and 2D projection when magnetic ordering vector is perpendicular to sample surface. c, same as b, but for magnetic order parallel to the sample surface. Blue arrows point to parts of the surface states that exist outside the areas where bulk electron shadow band overlaps with bulk hole pocket.
