A giant negative electrocaloric effect in Eu-doped PbZrO3 thin films

Author affiliations

Abstract

A negative electrocaloric effect (ECE) in 4 mol% Eu-doped PbZrO3 antiferroelectric (AFE) thin films prepared by using a sol–gel method is investigated via indirect measurements. Temperature dependent PE hysteresis loops were measured. A giant negative electrocaloric temperature change of over 6.6 K was observed. These results raised hopes for the enhancement of the cooling efficiency in combination with positive ECE.
