Quenched fields conjugate to polarization are found, which show mesoscopic (similar to 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.||Funding Details:||Other funder||Type of material:||Journal Article||Publisher:||AIP Publishing||Copyright (published version):||2009 American Institute of Physics||Keywords:||Polarization;Switching spectroscopy piezoresponse force microscopy;Nanoscale domains;Spatial variation||DOI:||10.1063/1.3222868||Language:||en||Status of Item:||Peer reviewed|
