Electronic structure and Fermi surface ofCrO2

Abstract
We report the results of an all electron self-consistent calculation of the electronic structure of CrO2 in the local spin-density approximation, employing an extended version of the linear combination of Gaussian orbitals method. CrO2 is found to be a half-metallic ferromagnet in agreement with previous calculations and recent experiments. The predicted Fermi surface is described in detail.
