The spin, orbital, and dipole magnetic moments were investigated using the LDA+U correlated band theory. We show that the around-mean-field LDA+U reproduces the x-ray magnetic circular dichroism experiments well and does not lead to the formation of a large orbital moment on the Fe atom. Furthermore, exact diagonalization of the multiorbital Anderson impurity model with the full Coulomb interaction matrix and the spin-orbit coupling is performed in order to estimate the spin Hall angle. The calculations suggest that there is no giant extrinsic spin Hall effect due to scattering on iron impurities in gold.
