Atomic Pair Distribution Function (PDF) is a one of local structure analysis. PDF analysis is a powerful method for ferroelectrics in which domain structure exists. A deviation arises between average and local structures under the influence of the ferroelectric domain configuration. The local structure analysis of BaTiO3 and BiMg0.5Ti0.5O3 is shown as an example of application to the ferroelectric materials of PDF analysis.
