Аннотация: Using the data about the temperature-pressure phase diagram and the phase transition entropy at ambient pressure, intensive Delta T-AD and extensive Delta S-BCE barocaloric effects were estimated near structural order-disorder phase transitions in oxyfluorides Rb2KTiOF5 and (NH4)(2)NbOF5. It was found that hydrostatic pressure is aПоказать полностьюn effective tool to change the entropy of compounds with ordering ionic groups in structure and to realize the significant caloric effects comparable with the values of electro- and magnetocaloric effects, characteristic for a number of materials, considered as promising solid refrigerants.
