First principles periodic Hartree-Fock calculations of the first ionis
ed state of Fe0.125Ni0.875 are reported from which the Mulliken popula
tions, charge and spin distributions and atom projected densities of v
alence band states provide direct evidence of Fe(3d) holes in complete
agreement with recent conductivity measurements on materials with app
roximately the same composition. This is in marked contrast to the sel
f-trapped hole in NiO also reported here, and the bound hole in Li-dop
ed NiO where both experiment and a recently reported calculation find
holes of predominantly O(2p) character.
