چکیده

It has been widely accepted that electric fields favor the ferroelectric phase with parallel electric dipoles over the antiferroelectric phase. With detailed measurements in polycrystalline ceramics of Pb(0.99)Nb(0.02[(Zr(0.57)Sn(0.43)(1-y)Ti(y)](0.98)O(3), we demonstrate in this Letter that electric fields can induce an antiferroelectric phase out of a ferroelectric phase, i.e., trigger an apparently unlikely ferroelectric-to-antiferroelectric phase transition. We suggest that it is caused by the volume contraction from the converse piezoelectric effect at the coercive field with a reversed polarity.

Antiferroelectricity induced by electric field in NaNbO3-based lead-free ceramics

Electric fields are known to favor a ferroelectric phase with parallel electric dipoles over an antiferroelectric phase. We demonstrate in this Letter that electric fields can induce an antiferroelectric phase out of a ferroelectric phase in a NaNbO3-based lead-free polycrystalline ceramic. Such an unlikely ferroelectric-to-antiferroelectric phase transition occurs at fields with a reversed pol...

THE ELECTRIC FIELD-INDUCED ANTIFERROELECTRIC TO FERROELECTRIC PHASE TRANSITION IN SOME (Pb,La) Zr0.55Ti0.4503 CERAMICS

Lanthanum substituted lead zirconate-titanate (PLZT) ceramics of composition 11.1/55/45 have been studied by measuring high electric field properties. Dc bias, dielectric and P-E hysteresis loop measurements have been employed to construct an E (electric field) versus T (temperature) phase diagram. At lower temperatures and small electric fields an antiferroelectric phase with tetragonal symmet...

Antiferroelectricity in oxides: a reexamination

The fundamental physics of antiferroelectric oxides and their properties are reviewed. First, the difficulties in formulating a precise definition of antiferroelectricity are discussed, drawing on previous discussion in the literature. We arrive at the following definition: an antiferroelectric is like a ferroelectric in that its structure is obtained through distortion of a nonpolar high-symme...

The electric field-induced antiferroelectric-to-ferroelectric phase transition is investigated through detailed measurements of electric polarization P, longitudinal strain x33, and transverse strain x11 developed under applied electric fields in a series of Pb0.99Nb0.02[(Zr0.57Sn0.43)1−yTiy]0.98O3 ceramics with compositions close to the antiferroelectric/ferroelectric phase boundary. It is fou...

Suppression of the antiferroelectric phase during polarization cycling of an induced ferroelectric phase

The ceramic Pb0.99Nb0.02[(Zr0.57Sn0.43)0.92Ti0.08]0.98O3 can exist in either an antiferroelectric or a ferroelectric phase at room temperature, depending on the thermal and electrical history. The antiferroelectric phase can be partially recovered from the induced ferroelectric phase when the applied field reverses polarity. Therefore, polarization cycling of the ferroelectric phase in the cera...
