Abstract
Abstract Field induced reversible transitions between AFE and FE phases of PLZT ceramics are considered to realize a high contrast image storage and display device. The proposed field-induced phase transition takes the material from a non-scattering AFE phase to a scattering FE phase, and returns the material to the original AFE phase by the application of a reverse field. The transitions can be accomplished by relatively low electric fields of several kV/cm. The required double hysteresis loops which indicate the reversible phase changes between AFE and FE phases were obtained in the composition of PLZT-7.6/70/30. Typical characteristic features accompanying the phase transitions are explained in terms of the phase relations of PLZT ceramics.
