Assessing local structure in PbZn 1/3 Nb 2/3 O 3 using diffuse scattering and reverse Monte Carlo refinement
We use an extensive X-ray diffuse scattering dataset collected from the relaxor ferroelectric PbZn1/3Nb2/3O3 to study the feasibility of refining a nanoscale structure with the reverse Monte Carlo method. Six integer and non-integer reciprocal sections are used with a total number of nearly 105 symmetry-independent data points. Very good agreement between observed and calculated diffuse scattering patterns is achieved with rather subtle diffuse intensity modulations being satisfactorily...[Show more]
