Temporal Evolution of the Electrical Energy of Rb2ZnCl4 Crystal as a Function of Polarization in the Ferroelectric Phase near the Curie Temperature

The repolarization of Rb 2 ZnCl 4 crystal under the influence of a harmonic electric field in the ferroelectric phase near the Curie temperature is studied via harmonic analysis. Study of the current density harmonics allows construction of the dependence of the density of electrical energy on polarization measured in the dynamics, and investigation of the temporal evolution of this dependence after destabilization of the domain structure by an alternating electric field. It is found that the nature of this dependence varies considerably during relaxation.
