摘要：

The value of the surface spin magnetic moment of Fe(100) is obtained by measuring the energy spread of the photoemission dichroism spectra of Fe3p core levels from bulk and surface. The bulk and surface signals have been resolved exploiting the photoemission diffraction effects in a linear magnetic dichroism of the angular distribution (LMDAD) experiment with soft X-rays. The LMDAD lineshape and energy width of the bulk contribution has been independently obtained from angular and from photon energy dependent experiments: it provides a gauge for determining the magnetic moment of the surface Fe3p atoms in the hypothesis of a linear dependance between energy width of dichroism and local spin magnetic moment.
