Description:
We present a strong electric-field-induced light scattering phenomenon in relaxor ferroelectrics 75Pb(Mg 1/3 Nb 2/3 )-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.
