• The core level electron energy loss spectra of nominally tetravalent CrO2 and trivalent Cr2O3 were measured. The Cr-L multiplet structure of CrO2 did not show a distinctly different spectrum from that of trivalent Cr2O3, although transition metal L spectra generally vary strongly with the oxidation states. The difference of the oxidation states was clearly observed in the O-K spectra in contrast to the Cr-L spectra. The O-K energy loss near edge structures revealed that the lowest conduction band of CrO2 has a large oxygen 2p component. It is concluded that the weak valence dependence of the Cr-L spectra is due to the relatively large d3L component in the electron configuration of CrO2.
