The domain structure of ferroelectrics changes during poling has a direct influence on the macroscopic properties of the materials. The intensity variation of the different X‐ray diffraction (XRD) pattern profiles was used to identify the percentage of 90° domain reorientation in the tetragonal phase of Pb(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PMN–PT) ceramics after poling. The results are consistent with the change of piezoelectric properties. In addition, by using XRD patterns, a spatial distribution of polarization in a well‐poled 0.62PMN–0.38PT ceramics has been determined and was found to be best described by the Cauchy function W 00l (ϕ)=1/(1+0.023ϕ 2 ).
