Abstract In the Ba_xSr_l-xTiO₃ system, the decrease of the grain size causes the suppression of the ferroelectricity and the increase of the relaxation frequency. Barrier heights increase with the increasing grain size. The result is analogous to magnetic phase transitions in nanocrystals and the solid-solid phase transitions in nanocrystals.
