DOI: 10.1103/physrevb.101.174108
Abstract: Short-range ordered polar nanoregions are key to the giant electromechanical properties exhibited by relaxorferroelectrics. Stabilization of the long-range ferroelectric order in relaxor systems has typically been achievedby applying external fields. In this work, spontaneous (zero-field)… read more here.
