Fig. 4: Orbital resolved band structures of (π, π, π) AFM phase with different values of Hubbard-U.
From: Electronic and magnetic structure of infinite-layer NdNiO2: trace of antiferromagnetic metal

The first, second, third, and forth row represents Nd, spin-up Ni, spin-down Ni, and O, respectively. The filled circles with different colors have the same meaning as those in Fig. 1. The name of d orbitals in the AFM supercell has been aligned to that of unit cell.
