Long-range interface roughness correlation in Ni–Ti neutron supermirrors is found to manifest in plateaus and peaks in the diffuse neutron scatter. The features are of resonant character and are strongly dependent on the type of the supermirror structure (slowly increasing or decreasing bilayer thickness). Distorted wave Born approximation calculations yield the statistical parameters of the interface roughness correlations.

Synergetics and respective advantages of nuclear resonant scattering of synchrotron radiation and of quasielastic neutron scattering are discussed on the basis of recent developments in the studies of diffusion in intermetallic alloys.

A comparison between the resonant scattering curve obtained by anomalous small-angle X-ray scattering at the X-ray absorption edge of Ni and the small-angle neutron scattering curve from an Al89Ni6La5 alloy sample is reported. It is shown that the two curves are proportional to each other and to the Ni-Ni partial structure factor.

Originally conceived for protein crystallography, contrast variation has become a favourite tool of small-angle scattering. Recent developments in contrast variation are reviewed.

A method is reported to determine the phase and amplitude of sinusoidally modulated event rates, binned into four bins per oscillation, based on data generated at the resonant neutron spin-echo spectrometer RESEDA at FRM-II.

Description of the helium-3 fridge insert at beamline P09 at PETRA III and demonstration of its workability in a synchrotron X-ray beam at a third-generation synchrotron source for the purpose of X-ray diffraction and resonant X-ray magnetic scattering at sub-Kelvin temperatures in high magnetic fields.

Spin-contrast-variation neutron reflectivity can be used to obtain multiple reflectivity curves from a single sample and a single beam source. This advantage of the technique allowed a structural analysis of the interface in a bilayer film comprising layers of acrylic urethane resin and methylated-perhydropolysilazane-derived silica (MePDS). It is revealed that, although the MePDS layer has a higher porosity near the interface with the resin, the resin did not permeate the pore network.

Sinusoidal wave type distortions of La0.5Sr1.5MnO4 in the low-temperature orthorhombic phase were observed using multi-beam resonant X-ray diffraction and dynamical theory.
