Abstract
Disorder and atomic diffusion are closely connected and these phenomena are the subject of investigations with numerous methods in our laboratory. We will report experiments on diffuse neutron scattering caused by the disorder in a strongly non-stoichiometric iron oxide, which leads to the formation of defect clusters and is related to diffusion and ion conductivity. Secondly, we will present results on quasielastic scattering for a water-doped perovskite with hydrogen atoms randomly bound at OH-ions. This material exhibits the interesting effect of proton conduction. The experiments were carried out on the spectrometers for diffuse scattering (DNS) and for peV-spectroscopy by backscattering (BSS1), both in the FRJ-2 guide laboratory ELLA.
