Origin of large negative electrocaloric effect in antiferroelectric PbZr O3

We have studied the electrocaloric response of the archetypal antiferroelectric PbZr O3 as a function of voltage and temperature in the vicinity of its antiferroelectric-paraelectric phase transition. Large electrocaloric effects of opposite signs, ranging from an electrocooling of −3.5 K to an elec...
