Influence of voltage amplitude parameters on the electrocaloric response in ferroelectric materials


Direct electrocaloric effect of BaTiO3-based ceramic materials was measured during poling and partial reverse poling using a square-wave electric field. A strong influence of the amplitude of the reverse bias field on the electrocaloric response was found. With increasing amplitude of the reverse bias field, the electrocaloric response was suppressed depending on the coercive field of the material and nature of the ferroelectric-to-paraelectric phase transition.
