Abstract:
Polarization (ferroelectric switching) of SBN crystals in pulsed fields differs from the same process in model ferroelectrics. Polarization in most SBN crystals is characterized by slow kinetics, which can be approximated by a power-law dependence, with relaxation times of the order of seconds (in fields
