Abstract

In situ piezoresponse force microscopy (PFM) imaging reveals highly non-linear kinetics of the superdomain boundary separating two a-c-domain bundles in BaTiO₃ lamellae. It is suggested that this behavior is caused by an unscreened depolarizing field of newly switched domains that counter balances the driving force from the applied electric field.
