摘要
Various epitaxial Fe(100)/Cr film structures were MBE-grown on MgO(100) and GaAs(100) substrates with the aim to modify the roughness of the Fe/Cr interfaces. By introducing a 2 monolayer thick Fe-57 probe layer at the interface the distribution of the magnetic hyperfine (hf) fields could be measured locally by means of Fe-57 conversion electron Mossbauer spectroscopy (GEMS). A simple model is applied which allows the determination of a pattern of the average interface roughness from this hf field distribution. It was observed that even samples of high epitaxial quality according to LEED and RHEED reveal a micro-roughness on a lateral scale of 1-2 nm due to intermixing of Fe and Cr within 1-2 monolayers.
