The dielectric response of electrostrictive (1− x) PMN– xPZT ceramics

The dielectric and pyroelectric properties of PMN–PZT ferroceramics in the area below temperature of a maximum dielectric permittivity ( T m ) were investigated. It is detected that temperature of transition from the ferroelectric phase into dipole-glass phase coincides exactly with the temperature...

Zusammenfassung:The dielectric and pyroelectric properties of PMN–PZT ferroceramics in the area below temperature of a maximum dielectric permittivity ( T m ) were investigated. It is detected that temperature of transition from the ferroelectric phase into dipole-glass phase coincides exactly with the temperature of the maximum of repolarization currents. The reasons for the appearance of repolarization currents and correlation of dielectric and pyroelectric properties are considered.
