Electrocaloric effect at special points in the composition-temperature-electric field phase diagram of barium zirconate-titanate (BZT)

Nikola Novak et al.

Summary: The composition-temperature-electric field diagram and electrocaloric properties of BaTi1_xZrxO3 (BZT) were calculated. The adiabatic temperature change due to material polarization at critical end, tricritical, and phase convergence points was quantified. The largest temperature change occurred at the first-order paraelectric to ferroelectric transitions, while the greatest material polarization contribution was observed at the critical temperature. The maximum electrocaloric responsivity occurred at a field 1.25 times greater than the critical field. The enhanced temperature change near the convergence point was attributed to greater polarization change in the rhombohedral phase and a polar glasslike state that contributed to the dipolar configurational entropy.

Hong Tao et al.

Summary: This paper introduces a new strategy based on phase engineering, which successfully enhances the electrocaloric effect in potassium sodium niobate ceramics. By lowering the polarization energy barrier and strengthening the reversion effect, a strong electrocaloric effect is achieved with a broad temperature range. An unusual trend in the electric field dependence is also observed.
