Abstract
The electronic and magnetic behavior of Co(0001) thin films on W(110) was investigated by means of Magnetic Circular Dichroism in the Angular Distribution of photoelectrons (MCDAD). It was found that significant photoelectron intensity differences occur for electrons emitted from the 3d bands near the Fermi level in the situation of a fixed photon helicity of the incoming circularly polarized radiation and opposite magnetization of the magnetic layer. The corresponding MCDAD asymmetry shows a significant dependence on the excitation energy in the VUV range and exhibits values up to about 8%. Emission from bands with majority and minority character results in asymmetry values of opposite sign. The different dispersion properties of these bands lead to different behavior of the corresponding asymmetry.
