Аннотация: Structural, calorimetric, dielectric, and electrocaloric investigations of Rb (x) (NH(4))(1 - x) HSO(4) ferroelectric solid solutions have been performed. It has been found that rubidium atoms inhomogeneously occupy nonequivalent crystallographic positions in the structure P2(1)/c. The influence of the rubidium concentration on theПоказать полностьюsequence of phase transitions in the NH(4)HSO(4) compound has been established. It has been revealed that the consequences of the Landau theory can be applied to the description of the temperature dependences of the anomalous heat capacity and the electrocaloric effect over a wide range of temperatures. Comparative evaluations of the electrocaloric and barocaloric effects in hydrosulfate and triglycine sulfate crystals have been carried out.
