Abstract—A new method is proposed for studying relaxation and transient processes in ferroelectric ceramics under the influence of a constant electric field. Precision measurements of the time dependences of the complex permittivity 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 characterizing relaxation processes in ferroelectric ceramics has been carried out. A physical interpretation of the results is proposed.
