DEPTH-SELECTIVE CONVERSION ELECTRON MOSSBAUER-SPECTROSCOPY OF AG FE-57/AG(111) SANDWICHES GROWN BY SPUTTERING/

DS-CEMS experiments were carried out on sputtered Ag/Fe/Ag sandwiches using enriched Fe-57 iron and selecting the electrons that emerge from the sample with 6.80 and 7.27 keV. Three iron components were identif ied: alpha-Fe, iron oxide and amorphous iron. The signals of these thr ee phases were fitted by a model describing the layer profiles: small iron oxide particles located at the top of the iron layers were uncove red with silver in S2 and covered with a thin silver layer in S3 and S 4; an amorphous phase seems to be stabilized within the interfacial zo nes and could be involved in the strong interface-induced anisotropy K (s) found by FMR.
