英文摘要For perovskite ferroelectric oxides, the composition-induced transition from ferroelectrics to relaxors can enhance their electrostrictive coefficient Q(33) remarkably, and has been attracting more and more attention in recent years. Achieving a larger electro-strain response is one of the most original driving forces for pursuing higher Q(33) values, while the two are often incompatible. Herein, taking the promising relaxor ferroelectric Na0.5Bi0.5TiO3 (NBT) as the research object, we report the excellent electrostriction-like electro-strain behaviors (0.41% <= S-uni <= 0.46%, 25 <= T <= 125 degrees C; S-uni exhibits only 2.23% decline after 105 cycles) together with a series of enhanced Q(33) values (0.029-0.047 m(4) C-2). Accompanied by the reconstruction of de-coupled A-O interactions, the electric-field-induced relaxor to ferroelectric state transition contributes to the superior electro-strain behaviors, while the enhanced Q(33) will greatly degenerate during this transition process. In contrast to the non-hysteretic electrostriction observed in linear dielectrics, for NBT-based relaxor ferroelectrics, the peculiar coexistence of ferroelectric in-phase a(0)a(0)c(+) and anti-phase a(-)a(-)a(-) tiltings is suggested to contribute to the enhanced electrostriction-like behaviors observed in this work. These observations indicate that NBT-based systems can be considered as a potential family of peculiar lead-free electrostrictors for application in the field of actuators.
