Abstract
New approach to a relaxor theory is developed. The localization of charge carriers on local centers play an important role in this theory. Localized charges create local electric fields which stimulate occurrence of induced polarization. After phase transition spontaneous polarization is directed along the local fields. Temperature behavior of the dielectric permittivity is determined by the dynamics of charge carriers localization on the local centers. Dispersion of the dielectric permittivity is determined by vibrational properties of the local states. The delay time of phase transition at field after cooling at zero field is also described.
