摘要

Polarized Raman spectroscopy has been performed to investigate the effects of the electric field on 0.68PbMg_1/3Nb_2/3O₃-0.32PbTiO₃(PMN-32PT) relaxor single crystal. Based on the group theory analysis, the Raman modes of PMN-32PT single crystal at zero-field are assigned to the monoclinic structure. The electric-field-evolution of Raman spectra reveal that a structural transition to tetragonal phase is initiated at a threshold electric field E₁and completed at higher field E₂. In the intermediate field range from E₁to E₂, the structure of the crystal is determined to be a coexistence of monoclinic and tetragonal phases. These results of the Raman spectra allow us to better understand the field-induced ultrahigh macroscopic strain in the relaxor ferroelectrics.
