摘要

Abstract

Here the BaTiO3 nanoceramics (BTNs), with 15 nm grain size, have giant electrocaloric effect. Most importantly, BTNs have the cooling per unit field about 3.95 at Tc =114°C under ∆E = 100 kV/cm. Moreover, the adiabatic temperature change of BTNs with 15 nm grain size under electric field shifts of 10, 50, 100 kV/cm are larger than one of BaTiO3 bulk and BaTiO3 thin film (T = 1.3 K).
