Giant electrocaloric effect around T$_c$

open access: yes, 2012
We use molecular dynamics with a first-principles-based shell model potential to study the electrocaloric effect (ECE) in lithium niobate, LiNbO$_3$, and find a giant electrocaloric effect along a line passing through the ferroelectric transition.

LARGE ELECTROCALORIC EFFECT IN RELAXOR FERROELECTRICS

open access: yesJournal of Advanced Dielectrics, 2012
Organic and inorganic relaxor ferroelectrics used for electrocaloric effect (ECE) applications are introduced. Relaxor ferroelectrics offer several advantages for ECE devices, e.g., infinite states without applying electric field, field-induced large polarization, no-hysteresis of heating and cooling, small-hysteresis polarization loss, room ...

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Two Consecutive Negative Electrocaloric Peaks in <001>-Oriented PMN-30PT Single Crystals

open access: yesCrystals
The versatile electrocaloric (EC) behaviors of the (1-x)Pb(Mg1/3Nb2/3)O3-xPT (PMN-100xPT) single crystal are closely related to the multiple phase transitions under the multiple fields of electric field and temperature.

Room temperature giant electrocaloric properties of relaxor ferroelectric 0.93PMN-0.07PT thin film

open access: yesAIP Advances, 2013
In this paper, 0.93PMN-0.07PT thin film shows a giant electrocaloric effect at room temperature. At electric field shift of 723 kV/cm, the peak value of ΔS of 0.93PMN-0.07PT thin film is 13.05 J/K.kg. The largest change (12.24 °C in 15.18 V, i.e. 0.8 K/V)
