The study of relaxation and transient processes in ferroelectric ceramics using the method of impedance spectroscopy

A new method for studying relaxation and transient processes in ferroelectric ceramics under the influence of dc electric field is proposed. Precision measurements of time dependences of complex dielectric constants of ferroelectric ceramics in the region of weak electric fields were carried out using the method of impedance spectroscopy. A comparative analysis of various methods for characterization of relaxation processes in ferroelectric ceramics is carried out. A physical interpretation of the results is proposed.
