|Title:||Photoelectron Spectroscopy Studies of Cr(001) Near-Surface and Surface Magnetism|
|Published:||February 01, 1986|
|Abstract:||Angle-resolved photoelectron spectroscopy (ARPES) studies of Cr(001) near-surface and surface electronic structure are reviewed. The near-surface energy band dispersions were investigated along the  direction parallel to the crystal surface. The periodicity of these band dispersions indicates that the valence electrons experience and self-consistently establish antiferromagnetism in the near-surface layers of Cr(001). Two surface-sensitive photoelectron peaks are observed in normal-emission ARPES. The spectral characteristics of these surface-related states are consistent with calculations that predict a ferromagnetic Cr(001) surface phase. The temperature dependence of one of these features is interpreted as evidence for a Cr(001) surface magnetic phase transition.|
