Comparison of the corrected specular XRR curves: measurements (+) and simulations (thick lines).
XRD patterns of ML1 (a) and ML2 (b) multilayers at different temperatures. For clarity, the spectra are shifted along the intensity scale. The peaks of the stainless-steel holder are marked with . The arrows mark the position of the FePt peak.
Dependence of the relative intensity of the satellite on temperature for ML1 (a) and ML2 (b) samples. The dotted lines are fits to the data.
Dependence of the average FWHM of the satellite on temperature for ML1 (a) and ML2 (b) samples. The dashed and dash-dotted lines are only guides for the eyes.
