Abstract
[Fe6Co3] and [Fe5Co5] superlattices have been studied by CEMS and time dependent nuclear resonance scattering in grazing incidence Bragg reflection geometry. CEMS shows hyperfine fields (B hf) between 33 T and 37 T. The time spectra of reflectivity allows us to separate contributions from different 57Fe monolayers in a bilayer. Contrary to our expectations the largest field is in the center of the Fe layers. The spontaneous orientation of B hf is along [1 1 0] in the layer plane.
