摘要：

Electrocaloric effect (ECE) of pure and modified PbSc1/2Ta1/2O3 (PST) and its solid solutions and PbMg1/3Nb2/3O3 - PbTiO3 ferroelectric ceramics is studied at different temperatures and external electric field intensities. High value of (ECE) up to 2.3 K is observed in PST ceramics at modification in B sublattice by Co3+ and Sb5+ ions. The features of ECE in PST are explained by significant structure rearrangement at electric field induced Fm3m --> R3m phase transition and high long range ordering of B ions in the ABO(3) perovskite structure. A further increase of ECE is observed in ceramic multilayer capacitors at higher electric field intensities up to 138 kV/cm.
