CrO₂predicted as a half-metallic ferromagnet

This is the authors' abstract. We don't add key points for this paper.

The band structure of chromium dioxide, which is an important material because of its magnetic properties, has been calculated with the augmented spherical wave method by performing self-consistent spin-polarised calculations. The majority-spin electrons are metallic, whereas the minority-spin electrons are semiconducting. A new class of half-metallic ferromagnets is found in the rutile structure.
