AbstractPolarization and transmission electron microscopy studies of the Pb La(ZrSnTi )O (PLZST) ceramics confirmed the antiferroelectric (AFE) nature of this material. The electric-field-induced ferroelectric (FE) phase has a lifetime much longer than the reasonable laboratory time scale at T∈≤∈60°C. The observed frequency dispersion of the dielectric constant reflects the competition between AFE and FE orderings. At high temperatures, the induced-FE phase reverses fast to the AFE phase. This process produces a pronounced pyroelectric current. The FE-to-AFE transition temperature can also be tuned by a dc bias field. © 2007 Springer Science+Business Media, LLC.
