摘要：

An advantages of lead based ferroelectrics are a high values of polarization and adiabatic temperature changes due to electrocaloric effect. In this paper dielectric properties and electrocaloric effect in ceramics based on solid solution of lead magnesium niobate-lead zinc niobate Pb((Mg0.8Zn0.2)(1/3)Nb-2/3)O-3(0.8PMN-0.2PZN) has been investigated. Values of electrocaloric effect reached 0.21 K with field change triangle E of 7 V/um.
