Abstract
Angle-resolved-photoemission measurements were performed on the Cr(110) surface at temperatures below and above the Néel temperature. The results are compared with previously calculated band structures, and for the antiferromagnetic phase fairly good agreement is obtained assuming direct transitions. Differences observed in photoemission spectra recorded below and above the Néel temperature are discussed in terms of the magnetic phase transition. For the paramagnetic phase the results could not be fully accounted for by calculated bulk band structures; possible explanations of the observed discrepancies are discussed.
