Diffraction Anomalous Fine Structure (DAFS) and EXAFS measurements have been performed on a [Fe 0.7 Mn 0.3 /Ir(100)] 40 } superlattice at the K‐edges of Fe and Mn. Theoretical EXAFS spectra have been refined: a slight difference in the first neighbor distance suggests a non homogeneous distribution of the Mn in the alloy. The smooth features of the DAFS spectra have been modeled to study the composition and the strain profile along the growth axis.
