Fig. 4: Orbital-resolved Fe-3d band structure.

a–e DFT electronic structures of FM Fe₃Ge for the Fe moments (μ_Fe  ≈  2.2μ_B) aligned along the y-axis with spectral weight projected onto five Fe 3d orbitals, respectively. The red, yellow, green, blue, and turquoise colors represent the d_xy (a), \({d}_{{x}^{2}-{y}^{2}}\) (b), d_xz (c), d_yz (d), and \({d}_{{z}^{2}}\) (e) orbital characters, respectively. The DP1,2 and vHS1,2 below E_F, as well as the vHS3 slightly above E_F, are marked out in a.
