Abstract
Spin-resolved photoemission of polycrystalline CrO2 films shows 3d states with a nearly + 100 % spin polarization about 2 eV below the Fermi level (EF). Extremely low intensity is observed near EF. Our findings are in contrast to recent band structure calculations, predicting CrO2 to be a half-metallic ferromagnet.
