The Research of the Repolarization Process in Solid Solutions (Rb1 – xKx)2ZnCl4 by the Harmonic Analysis Method

Abstract

The reactive component \({{J}_{c}}(t)\) and the active component \({{J}_{g}}(t)\) time dependences by the harmonic analysis method of the current density \({{J}_{x}}(t)\) time dependences arising in the repolarization process in the studied samples in the ferroelectric phase under the action of an electric field \(E(t)\), whose amplitude is higher than the coercive one, are obtained. Obtained dependences analysis showed general regularities in the dynamics of the (Rb_1 – xK_x)₂ZnCl₄ crystals domain boundaries. The regularities of the defects influence on the nonlinear physical properties associated with the domain structure dynamics are revealed.
