Zusammenfassung:
Ultrathin epitaxial Fe films on Cu(100) with perpendicular
magnetization have been used as templates for the preparation of FCC
Fe/Cu/Fe trilayers. The magnetic anisotropy and the coupling of these
films have been studied by in-situ magneto optical Kerr effect
measurements and Kerr microscopy. The magnetic Coupling of both Fe
layers is found to be dominated by magnetostatic interaction.
Adsorbate-induced spin reorientation in the top layer also Causes spin
reorientation in the bottom layer. The governing role of the Fe-vacuum
interface for the magnetism of the whole trilayer is demonstrated. (c)
