A first-principle description of the magneto-optical Kerr effect (MOKE) of ultra-thin surface layer systems is presented, that is based on the concept of non-local layer-resolved optical conductivity and the corresponding solution of the Maxwell equations. This powerful approach allowed a detailed investigation of the system Au(001)/nFe/mAu that shows pronounced quantum-confinement effects. In particular insight into the spatial origin of magneto-optical properties was obtained and the reliability of simplified approaches could be checked that way for this important prototype surface layer system.
