ABSTRACT
The hysteresis area as a function of frequency of the time-varying external electric field—hysteresis dispersion—for ferroelectric Pb(Zr[sub 0.52]Ti[sub 0.48])O[sub 3] is measured, and the Monte-Carlo simulation on the hysteresis dispersion for a model ferroelectric lattice is performed too. We demonstrate the scaling behavior of the single-peaked hysteresis dispersion for the two ferroelectric systems, predicting a unique effective characteristic time for the domain reversal. This characteristic time shows an inversely linear dependence on the field amplitude as long as the amplitude is high enough that the reversible domain rotation response is negligible. © 2001 American Institute of Physics.
