Abstract

The spatial variability of polarization reversal behavior in the relaxor 0.9Pb (Mg_1/3Nb_2/3O₃)-0.1 PbTiO₃ crystal, is revealed on the ∼100 nm scale using switching spectroscopy piezoresponse force microscopy. Quenched fields conjugate to polarization are found, which show mesoscopic (∼100-200 nm) spatial fluctuations around near-zero bias values. The mapping of the stability gap of the bias-induced phase and conjugate random fields is demonstrated. The origin of the observed nanoscale domains and the field-induced part of the polarization are discussed.
