The theory of valence band X-ray emission spectroscopy (XES) is discussed in terms of spin-polarized fully relativistic multiple scattering. In comparison to the non spin-polarized case new theoretical features are presented with particular emphasis on the dependence of the intensity on the polarization of the emitted photon. Applications to the L3 XES of a Co monolayer on Cu(100) substrate as capped by a monolayer of various 3d, 4d, and 5d transition metals are shown since such overlayer systems display systematic variations of the magnetic moment in the Co layer as well as in the cap layer. These changes are clearly mapped in the calculated XES and discussed in terms of transition cross sections and local densities of states.
