Abstract

Coherent iron-copper multilayers of a wavelength of 2.5nm that were measured to be nonmagnetic were structurally characterised using high resolution and Fresnel techniques. A measurement of the tetragonal distortion from layer to layer and as a whole would allow an assessment of the degree to which the material exhibits any anomaly in its elastic behaviour. The modelling of the distortions requires however the measurement of the abruptness of the interfaces and this requires the quantification of the Fresnel contrast. The degree to which the measurements can be obtained to the required accuracies is considered.
