Direct visualization of antiferroelectric switching dynamics via electrocaloric imaging
Pablo Vales-Castro, Miquel Vellvehi, Xavier Perpiñà +8
The large electrocaloric coupling in PbZrO3 allows using high-speed infrared imaging to visualize antiferroelectric switching dynamics via the associated temperature change. We fin…

Origin of the Large Negative Electrocaloric Effect in Antiferroelectric PbZrO3
Pablo Vales-Castro, Romain Faye, Miquel Vellvehi +9
We have studied the electrocaloric response of the archetypal antiferroelectric PbZrO3 as a function of voltage and temperature in the vicinity of its antiferroelectric-paraelectri…
