Abnormal Electric-Field-Induced Light Scattering In Pb(Mg1/3nb2/3)O-3-Pbtio3 Transparent Ceramics

We present a strong electric-field-induced light scattering phenomenon in relaxor ferroelectrics 75Pb(Mg1/3Nb2/3)-25PbTiO(3) transparent ceramics under a weak threshold electric field, which is attributed to the abrupt growth of polar nanoregions above the threshold field with a significant change of local crystal symmetry, dielectric, and Raman response. These results provide further understanding on the electric field-induced domain behaviors and peculiar properties in relaxor ferroelectrics. (C) 2015 AIP Publishing LLC.
