Decoding polar order-disorder phenomena in (Pb,Ba)ZrO3

The aim of this study is to understand how local polarizations evolve during the composition and temperature driven phase transitions in (Pb,Ba)ZrO3 which exhibits a sequential transformation from antiferroeletric to ferroelectric, ferroeletric to relaxor ferroeletric and finally to a Dibye medium as a function of composition. For this study, we propose to use the GEM diffractometer in order to collect total scattering data at ambient and nonambient temperatures.
