Abstract

A relaxor ferroelectric Pb(Ni_1/3Nb_2/3)_0.5Zr_0.15Ti_0.35O₃ (PNNZT) ceramic was reported, designed upon an idea that the composition is selected to near a tricritical point of tetragonal, rhombohedral and pseudocubic phases. High dielectric tunability of 67%, simultaneously with high electrostriction strain of 0.319% and high electrocaloric strength (ΔT/ΔE) of 32.5 mK cm/kV are achieved, which make it a promising multifunctional material for applications in dielectric tunable, precisely controlled and electric refrigeration devices. This is endowed by the low energy barrier among the transitions of phases and strong relaxor ferroelectric activities around the tricritical point. This work provides a guide for the design of multifunctional ferroelectric materials and can promote the development of other multifunctional ferroic materials.
