Abstract
The magnetism of epitaxial fcc-Fe films deposited on Co(1 0 0) and sandwich ed between two Co(1 0 0) films was investigated by X-ray magnetic circular dichroism at various temperatures. The dependence of the Fe magnetism on th e film thickness is complex and qualitatively similar on Co(1 0 0) and in f cc-Co/Fe/Co(1 0 0) trilayers. The fcc-Fe film magnetization presents a pron ounced oscillation suggesting a partial antiferromagnetic ordering in the 5 -10 monolayers (ML) thickness range. The decrease in temperature down to 10 0 K does not exhibit any change in the magnetic properties of the Fe-film. The fcc-Fe films mediate an oscillatory, indirect coupling in Co/Fe/Co(1 0 0) structures that alternates in correspondence with the changes of the Fe magnetization. (C) 2001 Elsevier Science B.V.
