: In crystalline solid solutions, even a random distribution of species sharing the same crystallographic sites leads to intrinsic nanoscale clustering of unit-cell characteristics, such as composition, charge, strain, etc. In PMN-PT, a structure with a random distribution of Mg and Nb or Mg, Nb, and Ti would exhibit extended regions with net positive and negative electric charges. The chemical ordering tends to increase the size of these regions.
