Extended Data Fig. 6: Tight-binding calculations.
a, Tight-binding calculations of the bands derived from the V1 dxz (dashed curves) and V2 dyz orbitals (solid curves) in the nonmagnetic phase. b, Tight-binding calculations of the bands derived from the V↑ dxz (dashed curves) and the V↓ dyz orbitals (solid curves) in the magnetically ordered phase. Red and blue represent spin-up and spin-down polarizations. c, Schematic of the V↑ dxz and V↓ dyz orbitals, which form δ and π bonds, respectively, along the b axis.
