Abstract
Normal-emission photoelectron spectra were recorded from Cr(110) at 80 K (below the Néel temperature of TN=312 K) with photon energies from 20 to 120 eV. Assuming a free-electron final band, bulk energy-band dispersions along the [110] (M) direction normal to the surface are determined. The results are compared with previously calculated band structures for the antiferromagnetic phase. Contrary to earlier claims, we find no evidence for a valence-band satellite in Cr. Temperature-dependent studies were also presented that reveal the disappearance of an emission from the 3 initial-state band (corresponding to the G3 band in the paramagnetic phase) at temperatures above TN for a specific k region. This result is discussed in terms of the bulk magnetic phase transition.
