Electric field-induced antiferroelectric-to-ferroelectric phase transition in lead zirconate titanate stannate ceramics modified with lanthanum

Abstract

Results of measurements in situ of electrostrictive strain, dielectric polarization, dielectric constant, and crystallographic parameters as functions of applied electric field in the temperature range 20–200 °C of Pb0.97La0.02(Zr0.66Ti0.11Sn0.23)O3 composition are reported. The antiferroelectric to ferroelectric phase transition with large volume change ΔV=0.35 Å3 is shown to be the dominant mechanism of the field-induced strain. The microscopic nature of the switching mechanism and the variation of the strain versus polarization squared at various temperatures are discussed.

Giant electric-field-induced strains in lead-free ceramics for actuator applications – status and perspective

“…3(c) bottom [53]. This volume change is known to be the main cause of the electric-field-induced strain in antiferroelectric materials [79]. It is known that the electric-field-induced ferroelectric phase either converts back to antiferroelectric phase completely or stays partially as a metastable phase depending on the mechanical boundary condition that could impede the transition [77,78,80].…”

Effect of composition and pressure on dielectric property in the Sn-modified lead zirconate titanate ceramics

“…When the sample is poled from the antiferroelectric to ferroelectric, the configure of the microdomain changed to the higher energy situation, the unstable structure is sensitive to the external field, the more addition of the Sn, the lower the transformation pressure become. For some compositions [9], switching from the AFE to FE can be easily achieved by a large strain, it is believed that the strain caused by phase switching is mainly due to the change in the primitive perovskite cell [10,11], phase switching involves multiple steps including both structure transformation and domain reorientation [11]. When the test is under hydrostatic pressure, the similar situation happens.…”

Double Hysteresis Loop in BaTiO3-Based Ferroelectric Ceramics

“…Since then, the double hysteresis loop, one important macroscopic effect, has been regarded as a typical characteristic of antiferroelectric materials. This kinds of antiferroelectric behavior is also observed in Pb(Zr, Sn, Ti)O 3 and Pb(La, Zr, Sn, Ti)O 3 ceramics (Berlincourt, 1963(Berlincourt, , 1964Biggers & Schulze, 1974;Gttrttritja et al, 1980;Shebanov et al, 1994). Interestingly, the double hysteresis loops have been observed in BaTiO 3 (Merz, 1953), BaTiO 3 -based (Ren, 2004;Zhang & Ren, 2005Liu et al, 2006), (Na 0.5 Bi 0.5 )TiO 3 -based (Takenaka, 1991;Sakata & Masuda, 1974;Tu et al, 1994;Sakata et al, 1992), (Ba, Sr)TiO 3 (Zhang et al, 2004), KNbO 3 (Feng & Ren, 2007, 2008, BiFeO 3 (Yuen et al, 2007) and other lead-based perovskite ceramics such as Pb(Yb 0.5 Ta 0.5 )O 3 (Yasuda & Konda, 1993) , Pb(Fe 2/3 W 1/3 )O 3 -Pb(Co 1/2 W 1/2 )O 3 (Uchino & Nomura, 1978), Pb(Sc 0.5 Ta 0.5 )O 3 (Chu et al, 1993) and Pb(Co 1/2 W 1/2 )O 3 (Hachiga et al, 1985) over the past decades.…”
