Polarization dynamics over broad time and field domains in modified ferroelectrics

The dynamics of polarization switching have been investigated over extremely broad time (10(-8)<10(2) s) and field ranges for various modified Pb-based perovskite ferroelectrics. The results unambiguously demonstrate the presence of extremely broad relaxation time distributions for switching, which can extend over decade(s) in orders of magnitude in time.
