Аннотация: A comparative analysis of electrocaloric and barocaloric efficiency of order-disorder ferroelectrics Rb-x(NH4)(1-x)HSO4 and TGS is performed. A good agreement was found between intensive electrocaloric effects measured experimentally and calculated using electric equation of state. Barocaloric effects were evaluated analyzing the eПоказать полностьюxperimental data on heat capacity and T-p phase diagrams. In some crystals under study the same adiabatic temperature change can be produced by low pressure and rather high electric field.
