Förlag: American Physical Society
The electronic structure of high-quality CrO2(100) films was investigated by means of x-ray absorption and resonant photoemission spectroscopy at the 2p-3d excitation threshold. The obtained binding energy of the occupied Cr 3d states is in agreement with the results predicted within the local spin-density approximation using the dynamical mean-field theory L. Craco , Phys. Rev. Lett. 90, 237203 (2003). The reported data support a model of CrO2 as a half-metallic ferromagnet with strong electron-correlation effects.
