N2 - The hysteresis properties of ferroelectric PZT capacitors were investigated by measuring their cyclic current–voltage characteristics using a source-measure unit of a semiconductor device analyzer. The first-order reversal curve diagrams were obtained, which have a typical appearance for ferroelectric materials. Based on the obtained diagrams, the degree of correlation between the positive and negative coercive fields of ferroelectric domains was identified, and the deviations in their behavior from the Preisach model domains were determined. A peak-splitting phenomenon was observed, and some of its features were found.
