The cluster pseudospin model of proton glasses, which takes into account the energy levels of protons around the PO4 group, the long-range interactions between the hydrogen bonds, and an internal random deformational field is used to investigate thermodynamical characteristics, longitudinal and transverse dielectric permittivities of Rb1-x(ND4)xD2PO4 and Rb1-x(NH4)xH2AsO4 compounds. A review of experimental and theoretical works on the Rb1-x(NH4)xH2PO4 type crystals is presented.
Key words:
