Popis: Epitaxial [ Fe (0 0 1)/ Pd (0 0 1)] n multilayers are prepared onto sapphire substrates under ultrahigh-vacuum conditions. The topography and structure of the layers and their interfaces are characterized using in situ STM and RHEED and ex situ XRD. Although the lattice mismatch between the two materials amounts to about 4%, we find epitaxial growth up to n =32 bilayers. Our investigations reveal that with increasing Fe-layer thickness the iron lattice gradually changes from a face-centered tetragonal (fct) to a body-centered tetragonal (bct) structure.
