INFLUENCE OF MAGNETIC-ORDERING ON THE NIO VALENCE-BAND

The influence of magnetic ordering on the NiO valence band has been st udied 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 dep endence but no significant changes in the valence band structure are d etected in connection to the passing of T-N. The reported data suggest that the magnetic phase transition does not influence the valence ban d structure significantly.
