Query: Effects of Core-Hole Screening on Spin-Polarised Auger Spectra from
  Ferromagnetic Nickel   We calculate the spin- and temperature-dependent local density of states for
ferromagnetic Ni in the presence of a core hole at a distinguished site in the
lattice. Correlations among the valence electrons and between valence and core
electrons are described within a multi-band Hubbard model which is treated by
means of second-order perturbation theory around the Hartree-Fock solution. The
core-hole potential causes strong screening effects in the Ni valence band. The
local magnetic moment is found to be decreased by a factor 5-6. The
consequences for the spin polarisation of CVV Auger electrons are discussed.
