a Nonmagnetic phase. b Paramagnetic phase as modelled by the spin-SQS structure of the 1 × 2 × 2 supercell (48-atom) of the experimental monoclinic structure. The majority states are indicated in a, b. Blue area indicates the occupied states, among them the split-off flat-band states are indicated by bold red boundary.
