摘要：

The magnetic ordering of the topmost surface layer of Mn films grown on Fe(100) at different temperatures is investigated via the polarization of fluorescence light emitted after capture of spin-polarized electrons into excited atomic terms during scattering of 25-keV He+ ions. For coverages up to about 0.5 ML the observed spin polarization is in accordance with in-plane ferromagnetic order of Mn moments with antiparallel coupling to moments of the Fe substrate. For 1-8-ML films the detected spin polarization vanishes, indicating in-plane antiferromagnetic order of the topmost layer.
