The domain switching behavior of a substrate-free lead magnesium niobate-lead titanate thin sheet by an opposite electric field (E) was examined by piezoresponse force microscopy. It is shown that the polarization reversal process involved two steps. First, the polarization switched from the initial normal direction to an in-plane direction at -E<5 kV/cm. Second, at -E>5 kV/cm, the polarization was further switched from the in-plane direction to the opposite field direction. The preference of the in-plane polarization at -5 kV/cm was attributed to the thin-sheet geometry, which also manifested itself as a maximum in dielectric constant at the same field.
