The ground state total (black lines) and projected (gray shaded areas) density of states. The transition metal 3d-derived states for the majority and minority spins for the ground state magnetic moment are shown for (a) Sn0.96Fe0.04O2, (b) Sn0.96Fe0.04O1.98(VO)0.02, (c) Sn0.96Co0.04O2, and (d) Sn0.96Co0.04O1.98(VO)0.02. The vertical dashed lines correspond to the highest occupied energy level for the majority and minority spins.
