Differences in growth and magnetism between thin Fe films on vicinal and flat Au(111) — •Tobias Allmers and Markus Donath — Physics Institute, University of Münster, Wilhelm-Klemm-Str. 10, 48149 Münster

In this contribution we report on differences in growth behavior and magnetic properties of Fe films deposited on vicinal (v-) and flat Au(111). The different growth mode results in a different magnetic behavior: We found that the transition from out-of-plane to in-plane magnetization as a function of film thickness is delayed for the system Fe/v-Au(111) with respect to Fe/Au(111). Furthermore, we found no distinguished easy in-plane magnetization direction for Fe/Au(111), while the easy in-plane magnetization direction for Fe/v-Au(111) is perpendicular to the step edges. In addition, the spin-dependent electronic structure below and above the Fermi level was investigated with respect to the symmetry character and the sensitivity towards adsorbates of the respective spectral features.
