Multifractal analysis of electron beam stimulated process of polarization reversal in ferroelectrics

This work deals with the application of multifractal methods to the analysis of polarization switching processes in ferroelectrics. The ferroelectric polarization reversal current was considered as a dynamic response of finite system with fractal behavior. The problem of fractal characteristics estimation was solved using fractal theory methods designed for nonstationary time series. The results of multifractal analysis were examined for polarization switching current of triglycine sulphate crystal obtained from electron beam induced polarization current mode.
