Abstract
The influence of uniaxial compression on the electrocaloric effect in a barium titanate-based bilayer was studied using the Landau-Ginzburg thermodynamic approach. Barium titanate was used as a model material. It was shown that the electrocaloric effect can be controlled by uniaxial compression. Application of compressive stress is an effective approach to enhance the electrocaloric effect in ferroelectric ceramics. The compressive stress in the considered magnetostrictive-ferroelectric bilayer is a result of mechanical coupling between ferroelectric and magnetostrictive phases.
