  We report calculations of the band structures and density of states of the
four transition metal monoxides MnO, FeO, CoO and NiO using the hybrid density
functional sX-LDA. Late transition metal oxides are prototypical examples of
strongly correlated materials, which pose challenges for electronic structure
methods. We compare our results with available experimental data and show that
our calculations yield accurate predictions for the fundamental band gaps and
valence bands of FeO, CoO and NiO. For MnO, the band gaps are underestimated,
suggesting additional many-body effects that are not captured by our screened
hybrid functional approach.
