Real crystal op roshelle salt group domain dynamics and its contribution to low frequency dispersion of dielectric permittivity

Abstract

Experimental results of Roshelle salt group crystals dielectric spectra at ultra-low frequencies are discussed. In the vicinity of the phase transition point, the coexisting Cole-Cole type dispersion regions of dielectric permittivity are associated with the dynamics of defects of, both domain and non-domain nature. For the 180 plane domain structure model, the quantitative values of domain dynamics parametres in real crystals have been obtained.
