Neutron Diffraction

ND has been widely applied to study proton-conducting perovskites. More fre­quently, Rietveld refinement using conventional neutron powder diffraction data is applied, and in some cases, is used to understand how the structure may change with temperature and/or surrounding atmosphere. ND is of paramount importance for studies of proton-conducting perovskites due to its ability to determine proton sites, with both Rietveld and pair-distribution function (PDF) analysis of neutron total-scattering data being applied.
