(a) Fe K-edge EXAFS oscillations χ(k) from the multilayers and from the Py film. (b) FT (not corrected for phase shift) magnitude of k2-weighted Fe K-edge EXAFS oscillations. The contributions from Fe-O and Fe-(Fe, Ni) are indicated in the figure. The inset shows the FT from the PyO2 film and a Fe2O3 powder sample.
