Abstract :
The aim of the presented paper is to show that the application of analysis methods of dissipative chaotic systems is a useful tool for the study of structural phase transitions and the large signal behaviour of ferroelectric materials. The series resonance circuit with a ferroelectric capacitor is a practical realization of a nonlinear dynamical system which exhibits period-doubling behaviour and chaos if the amplitude and the frequency of the driving voltage have suitable values. The response function of the nonlinear dynamical system is used for the determination of the nonlinear coefficients of the sample
