Spin dependent scattering of electrons at interfaces is one of the most relevant microscopic processes that determine the performance of spintronics devices. However, the scattering process itself is hard to address experimentally. Here, we use spin-resolved momentum microscopy to investigate the scattering of photoelectrons from a Au(111) surface on Bi superstructures. We will show that the Bi/Au(111) interface constitutes a simple model system to understand spin dependent electron scattering processes on the microscopic level, since the spin polarization changes with the number and direction of scattering events.
