TLDR
In this paper, EXAFS data are presented to provide evidence that Pb is actually attracted to the larger B′ cations which are usually ferroelectrically inactive, leaving the smaller B″ cations relatively free of Pb-OB coupling.About:

A Bifunctional Perovskite Catalyst for Oxygen Reduction and Evolution
TL;DR: The dynamic microstructure phenomena are attributed to the charge imbalance from the replacement of A-site cations with La3+ and local stress on Cosite sub-lattice with the cubic perovskite structure.

Domain Growth in Pb(Mg1/3Ta2/3)O3 Perovskite Relaxor Ferroelectric Oxides
Mehmet A. Akbas,Peter K. Davies +1 more
TL;DR: In this paper, the authors report on experiments that have been conducted on the tantalate relaxor, Pb(Mg1/3Ta2/3)O3(PMT), and its solid solutions with PbZrO3, in which the size of the do-mains and the degree of cation ordering have been in-creased by two orders of magnitude through annealing that has been conducted at a temperature of 1325°C.
