Abstract: Epitaxial FeAl superlattices were used as nonmagnetic spacers in MgO(001)Fe/FeAl/Fe trilayers. The magnetic hyperfine field at the nuclei of a Fe-57 probe layer, situated in the center of the FeAl spacers, being a measure of the spin polarization from the ferromagnetic Fe layers, was investigated as a function of the total spacer thickness d. A decaying oscillatory dependence of the polarization effect vs. d was found. Magnetization measurements revealed the existence of a temperature dependent 90 degrees coupling. Finally, the correlation of the spin polarization and coupling behavior was clearly identified. (C) 2004 Elsevier B.V. All rights reserved.
