Abstract:

We have studied the polarization reversal process and analyzed the switching currents in KTiOPO4 single crystals with intermediate potassium content. The activation field dependence of the switching time has been revealed. Two stages of the polarization reversal have been distinguished during analysis of the switching current data. The first stage with smooth current corresponds to beta(2D)-process fitted by Kolmogorov-Avrami formula. The second stage with spikes in the switching current caused by intensive domain merging was analyzed by a modified Korcak method. The obtained value of the Hurst exponent indicated the weak persistence of the switching process with long-time correlation.
