Abstract
Resonant scattering of elliptically polarized soft x rays has been used to study the magnetic properties of Fe in the trilayer structure Cu-85/Fe-x/Cu -33 deposited on a Si(111) substrate. For x = 20 Angstrom, our room tempera ture data can be reproduced by calculations which assume the magnetic prope rties of bulk bcc alpha -Fe. For 2 less than or equal tox less than or equa l to6, our experiment indicates that Fe has a very small magnetic moment in the surface plane, which increases with thickness but remains below 0.2 mu (B).
