In situ piezoresponse force microscopy (PFM) imaging reveals highly non‐linear kinetics of the superdomain boundary separating two a‐c‐ domain bundles in BaTiO 3 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.
