Direct measurements of the electrocaloric effect in lead-free K0.5Na0.5NbO3-SrTiO3 ceramics sintered in air
By utilizing direct measurements of the electrocaloric effect (ECE) temperature change via high-resolution calorimeter, the ECE has been studied in bulk lead-free relaxor K0.5Na0.5NbO3-SrTiO3 (KNN-STO) ceramics. Observed magnitude of the ECE confirms existence of the large EC effect in this system near the ferroelectric phase transition.
