Аннотация: To establish the existence of dipole glass in the chromium-substituted bismuth pyrostannate solid solutions, the frequency and temperature dependences of the permittivity have been measured in the temperature range of 300-750 K. The field and dynamic dependences of polarization in the temperature range of 80-550 K have been determined. Using the Raman scattering spectra, the absence of inversion center has been established. The maximum of electrical resistance has been found in the vicinity of the dipole moment freezing point. The carrier type has been determined from the thermopower data. The polarization relaxation is shown to be nonexponential. The experimental data are explained within the model of dipole glass in the μ- phase and the model of charged crystalline domain walls with the electron-polarization relaxation mechanism above the μ-β structural transition. © 2018 IOP Publishing Ltd.
