Abstract

The relationship between electrocaloric effect (ECE) and electrostrictive strain over a broad electric field was studied in (1-x)(Sr_0.7Bi_0.2)TiO₃+x(Na_0.5Bi_0.5)TiO₃ relaxor based lead-free ceramics, where the electric field induced strain can reach the level of 0.28% at 12 MV/m. The experimental data revealed that the composition with highest strain response also generated the largest ECE near room temperature, e.g., ΔS=3.6 J kg⁻¹ K⁻¹ and an adiabatic temperature change ΔT=2.4 K at 13 MV/m. This research provides an effective approach for designing new ECE materials.
