Since the positive influences of defects on the performance of electroceramics were
discovered, investigations concerning on defects and aliovalent do** routes have grown …

The occurrence of the inverse (or negative) electrocaloric effect, where the isothermal
application of an electric field leads to an increase in entropy and the removal of the field …

Ferroelectric/antiferroelectric thin/thick films with large positive or negative electrocaloric
(EC) effects could be very useful in designing commercial refrigeration devices. Here, a …

(Pb0. 97La0. 02)(Zr x Sn0. 94–x Ti0. 06) O3 (PLZST) antiferroelectric ceramics with x= 0.75–
0.90 have been fabricated and found to be a novel electrocaloric material system with a …

The electrocaloric effect and energy storage property are tuned in the Ba 1-x Ce x Ti 0.99 Mn
0.01 O 3 ceramics prepared by the solid state reaction method. The ceramics with lower Ce …

We study the electrocaloric (EC) effect in bulk BaTiO 3 (BTO) using molecular dynamics
simulations of a first principles-based effective Hamiltonian, combined with direct …

Ferroelectric perovskite oxides possess a large electrocaloric (EC) effect, but usually at high
temperatures near the ferroelectric/paraelectric phase transition temperature, which limits …

The microstructure, dielectric property and electrocaloric effect were investigated in the lead-
free (1-x) BaTiO 3–x (BiMg 1/2 Ti 1/2) O 3 ((1-x) BT–x BMT, x= 0.0–0.05) ferroelectric …

We demonstrate a thermodynamic formulation to quantify defect formation energetics in an
insulator under a high electric field. As a model system, we analyzed neutral oxygen …

The present work demonstrates ferroelectric to antiferroelectric transition aided electric field
control of positive and negative electrocaloric effects (ECE). In this context, epitaxial PbZrO3 …
