dc.description.abstractWe show that the ferroelectric system (1−x) SrTiO3−(x) Na0.5Bi0.5TiO3 exhibits an interesting interplay of local polarization, ionic size effect, and octahedral tilt. This interplay results in (i) a nonmonotonic composition dependence of the lattice volume at room temperature and (ii) existence of a unique temperature (300∘C) at which the competing effects of electrostriction caused by the formation of polar nanoregions and geometrical ionic size make the system exhibit composition independent lattice parameters in a large composition interval x<0.40. ©2024 American Physical Society.en_AU
