Abstract
Abstract Dispersion of ∊∗ dielectric complex permittivity of Roshelle Salt (RS) poly-domain crystals has been investigated in ultralow frequency range of weak sinusoidal electric field. Two Cole-Cole type ∊∗ dispersion regions were found in RS polar phase. Effects of applied constant electric field and shering stress on the parametres of these ∊∗ dispersion regions and their temperature dependences have been analysed. The values of electric field, shearing stress and activation energy of electric polarization relaxation for both dispersion regions have been determined.
