Abstract: The results of research of the processes of polarization of niobium-containing crystals of barium titanate in changing electric fields are presented. It has been established that the time for reorganization of the ferroelastic domain structure is 30-40 times shorter than the switching time of the total polarization of the crystal, which indicates that the main switching time of BaTiO3 : Nb5+ crystals is determined by the change in its ferroelectric 180° domain structure.
Keywords: processes of switching, domain structure, barium titanate, polarization-optical method, Barkhausen effect.
