Figure 2.

Band structure of bulk F4GT: (a) spin-up bands and (b) spin-down bands. The width and color of the bands indicate the orbital character. Bands with Fe 3d_xz, 3d_yz, and 3d_z² orbital character are blue, green, and red, respectively. On the right-hand side of each band structure, we show the density of the states with momentum ℏk_z > 0 along the Γ-A direction in the Brillouin zone. The energy region around E_F is highlighted in red.
