Electric-field-induced AFE-FE transitions and associated strain/preferred orientation in antiferroelectric PLZST.

Electric-field-induced, antiferroelectric-ferroelectric (AFE-FE) phase transitions are common for AFE materials. To date, the strain and preferred orientation evolution as well as the role of the intermediate FE state during the successive AFE-FE-AFE phase transitions has not been clear. To this end, we have herein studied a typical AFE Pb0.97La0.02(Zr0.56Sn0.33Ti0.11)O3 (PLZST) material using ...

Field-induced phase transitions in antiferroelectric liquid crystals.

A theoretical study is made of the process by which an antiferroelectric smectic liquid crystal undergoes a field-induced transition to ferroelectric alignment. We find that for cells of moderate thickness the initial departure from antiferroelectric alignment occurs as a continuous Fréedericksz transition. The following transition from partial alignment to complete ferroelectric ordering may o...

Direct current field adjustable ferroelectric behaviour in (Pb, Nb)(Zr, Sn, Ti)O3 antiferroelectric thin films

Abstract (Pb,Nb)(Zr,Sn,Ti)O3 antiferroelectric (AFE) thin films have been fabricated on LaNiO3/Pt/Ti/SiO2/Si wafers using a sol–gel process. The electric field-induced antiferroelectric-to-ferroelectric (AFE–FE) phase transformation behaviour and its dependence on the temperature were examined by investigating the dielectric constant and dielectric loss versus temperature and electrical field. ...

Electric-field-induced transformation of incommensurate modulations in antiferroelectric Pb0.99Nb0.02[(Zr1â‹TMxSnx)1â‹TMyTiy]0.98O3

Most antiferroelectric ceramics are modified from the prototype PbZrO3 by adding Sn and Ti in conjunction with small amount of Nb or La to optimize their properties. These modifiers introduce unique nanoscale structural feature to the ceramics in the form of incommensurate modulations. It was shown previously that the modulation is strongly responsive to a change in chemical composition or temp...

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...
