Influence of magnetic ordering on the NiO valence band

The influence of magnetic ordering on the NiO valence band has been studied by angle resolved photoelectron spectroscopy. Measurements have been performed at temperatures above and below the Neel temperature (T-N), as well as at room. temperature. The results show temperature dependence but no significant changes in the valence band structure are detected in connection to the passing of T-N. The reported data suggest that the magnetic phase transition does not influence the valence band structure significantly.
