Size and orientation of polar nanoregions characterized by PDF analysis and using a statistical model in a Bi(Mg1/2Ti1/2)O3-PbTiO3 ferroelectric re-entrant relaxor
Revealing the local structure information of relaxor ferroelectrics is necessary for a clear understanding of their structure-property relationships, especially the determination of the size of polar nanoregions (PNRs), which is still a long-standing challenge. In this work, the local structure of the pseudo-cubic solid solutions 0.60Bi(Mg1/2Ti1/2)O3-0.40PbTiO3 and 0.65Bi(Mg1/2Ti1/2)O3-0.35PbTiO3,
