Nanometer transverse resolved real space observations of the initial phases of room-temperature heteroepitaxy of fcc Fe/Cu(100) indicate that vertical atomic site exchange occurs locally. The formation of two-dimensional supersurface and subsurface islands has been characterized by secondary and Auger electron imaging. The persistence of vertical site exchange during the deposition of the first two monolayers is not inconsistent with the lack of observed ferromagnetism for the room-temperature grown fcc Fe/Cu(100) at these coverages.
