Dielectric relaxation in Ba0.96Bi0.04Ti0.96Fe0.04O3
Journal of Applied Physics, 1998Samples of Ba0.96Bi0.04Ti0.96Fe0.04O3 were prepared by a solid state reaction method. Data on the dielectric constant as a function of temperature and frequency were obtained in the temperature range 35–180 °C at 10 and 100 kHz. The material shows a diffuse phase transition.

Dielectric relaxation of microemulsions
2007The complex permittivity of AOT/H2O/CCl4 and AOT/H2O/n-heptane microemulsions has been measured by a frequency domain coaxial techniques in the range 0.02/20 GHz as a function of the molar ratio [H2O]/[AOT] (W). A relaxation phenomenon was observed whose behavior vs.

Dielectric relaxation in polydialkoxyphosphazenes
Polymer Science U.S.S.R., 1982Abstract A study has been made of dielectric relaxation in six linear polydialkoxyphosphazene polymers with side methylene chains of differeing length. Transitions associated with localized and segmental forms of molecular motion were found in all the homologues.

Dielectric relaxation: an overview
Journal of Molecular Liquids, 2004Abstract The classical theory of dielectric relaxation of an assembly of polar molecules is briefly reviewed as a prelude to the derivation of the fractional diffusion equation, which is used to extend the Debye–Frohlich model of relaxation over a potential barrier to anomalous diffusion governed by the Cole–Cole equation.

Dielectric Relaxation in Nitroalkanes
The Journal of Chemical Physics, 1969Permittivity and dielectric loss (ε′ and ε″) of four nitroalkanes have been measured at five frequencies at 3, 15, 30, 45, and 60°C. The values of ε′ and ε″ have been used to plot Cole–Cole diagrams. The relaxation time and the distribution parameter have been calculated from these arc plots. It has been observed that the relaxation time increases with

Relaxational polarization of dielectrics
Soviet Physics Journal, 1979It follows from the foregoing that the main equations for the static and complex dielectric permittivity have now been sufficiently completely formulated, allowing the permittivity to be rigorously determined with short-range interaction taken into account.
