Abstract

Angle-resolved photoemission was used to study the surface electronic band structure of ferromagnetic CoS₂ (below 120K) in high-quality single crystal samples. Strongly dispersing Co t_2g bands are identified along the <100> k₁₁direction. Fermi level crossings are identified along this r̄-x̄ line (of the surface Brillouin zone) in higher resolution photoemission spectra, suggesting that the overall polarization may be controlled by the details of the band structure, particularly the surface band structure, rather than by exchange splitting on the Co atoms.
