Fermi surface of AFM-ordered EuRh2Si2 derived by UV-ARPES and DFT calculations. a 3D view and b top view of the calculated FS along kz. c Comparison of the projected bulk FS (top left panel) and the ARPES-derived FS (bottom right panel) taken at 10 K. The yellow dashed line depicts the border of the Brillouin zone. d Additionally to the projected bulk FS, the surface states and surface resonances have been extracted from slab calculations for Eu-termination (cyan, top left panel) and Si-termination (green, bottom left). The spin polarization of the termination-specific surface-related states is indicated in red and blue on the right side
