      abstract     = {The growth of up to ten-monolayer-thick Fe films on a
                      Au(001) surface was investigated during depositionat room
                      temperature and during annealing, using low-energy electron
                      diffraction and x-ray photoemissionspectroscopy, as well as
                      locally with low-energy electron microscopy and
                      photoemission electron microscopy.The growth proceeds with a
                      submonolayer of Au segregating on the surface of Fe, which
                      is in agreement withprevious studies. Annealing was found to
                      be critical for the presence of Au on the Fe surface. Our
                      study identifiesa spatially inhomogeneous Au segregation
                      mechanism which proceeds by the formation of cracks in the
                      Fe film,starting at the annealing temperature of 190 °C,
                      through which Au diffuses towards the surface. As a result,
                      asystem with a nonuniform surface electronic structure is
                      obtained. This study shows the necessity to employspatially
                      resolved techniques to fully understand the growth modes of
                      the layered epitaxial systems.},
