| Abstract: | Unmodified lead zirconate titanate stannate (PZST) system with compositional formula Pb (Zr0.7Sn0.3)xTi(1−x)]O3, where 0.92≤x≤0.94 has been studied at Morphotropic phase boundary (MPB) for dielectric, ferroelectric and shape memory effect. Field-induced strain measurements are presented to show that ∼0.08% remnant strain pertaining to shape memory can be observed in PZST ceramics at near-exact MPB. |
