Dipole glass in chromium-substituted bismuth pyrostannate

Abstract

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 αphase and the model of charged crystalline domain walls with the electronpolarization relaxation mechanism above the α-β structural transition.

“…In the vicinity of phase transitions, the system reveals large fluctuations of the order parameter. Phase transitions are realized in magnetic [1][2][3], crystalline [4][5][6] and dielectric [7][8][9] systems. In this temperature range, the system becomes unstable and nonequilibrium effects appear.…”

The effect of cation substitution on conductivity in the region of structural phase transition

“…Substitution can lead to distortion of the crystal structure and a shift of phase transitions. For example, heterovalent substitution of Bi3 + and Sn4 + ions in Bi2Sn2O7 leads to a changing of the of the α → β transition temperature [12].…”
