“…However, in area (c), the peak at 570 cm −1 in the VH geometry is only a weak shoulder, while the broad band centered at 780 cm −1 is very weak relative to that in the VV geometry. Such features suggest that the structure of this micro-area is in the M C -type monoclinic phase [14]. In the present work, we select (a) area to discuss the phase transition of 0.24PIN–0.43PMN–0.33PT single crystal.…”

Polarized Raman spectroscopy was performed to investigate the local lattice structure and phase transitions of unpoled 0.24Pb(In1/2Nb1/2)O3–0.43Pb(Mg1/3Nb2/3)O3–0.33PbTiO3 (0.24PIN–0.43PMN–0.33PT) single crystal in the temperature range from 30 °C to 260 °C. MA- and MC-type monoclinic phases were detected by micro-Raman spectra measured in different micro areas. Temperature dependence of Raman intensities, frequency shifts, mode merge and intensity ratios in the VV and VH geometries were investigated. Our results indicated that the monoclinic–tetragonal (M–T) phase transition of the ternary relaxorbased ferroelectric single crystal 0.24PIN–0.43PMN–0.33PT occurs at 85 °C, which is verified by the mode merging from 520 cm−1 and 580 cm−1 to 500 cm−1, and the tetragonal–cubic (T–C) phase transition happens at 200 °C based on the vanishing mode at 780 cm−1 measured in the VH polarization.

“…In particular, it has been a powerful tool in the investigation of structural characteristics of relaxors on the nanometer scale, such as polar nanoregions (PNR) and chemically ordered regions (COR) in relaxor ferroelectrics. [19][20][21][22][23][24][25][26] In addition, low-frequency (low-wavenumber) spectral range is very important because soft optic phonon mode and/or central peak (CP) can be probed and investigated in relation to the nature of phase transition behaviors and relaxation dynamics. [27][28][29] The motivation of the present study is to carry out systematic investigation of PIN-PMN-PT single crystals by using a high-resolution Raman spectroscopy with the high stray light rejection, including polarization effect, temperature, and angular dependences of vibrational spectra.…”

The broadband inelastic light scattering spectra of ternary Pb(In1/2Nb1/2)-Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals were investigated as a function of temperature and crystal orientation by combining Raman and Brillouin spectroscopies. The angular dependence of the strong Raman peak located at ∼50 cm−1 was investigated at 300 °C. The intensity variation of this mode with rotation angle was compatible with the F2g mode of Fm3¯m symmetry, suggesting that this mode arises from the 1:1 chemical order at the B-site in this perovskite structure. The temperature evolution of the polar nanoregions was associated with the growth of two central peaks and the change in the intensity of some Raman peaks, which were known to be sensitive to the rhombohedral symmetry. Both relaxation processes exhibited partial slowing-down behaviors with a common critical temperature of ∼160 °C. Poling the crystal along the [001] direction induced abrupt changes in some of the Raman bands at the rhombohedral–tetragonal phase transition. On the other hand, the diffuse tetragonal–cubic phase transition was not affected by the poling process. This high-temperature phase transformation seems to be smeared out by the inherent disorder and strong random fields enhanced by the addition of Pb(In1/2Nb1/2) into Pb(Mg1/3Nb2/3)O3-PbTiO3.

“…The field-induced M C -type to the M A -type monoclinic phase transition was identified at low E-field (E ¼ 5.8 kV/cm). 16 However, the E-field dependent Raman measurement on PMN-PT has not yet been presented across M-T phase transition. It is of interest to examine the differences in the phonon behaviors near and during this M-T transition.…”

Polarized Raman spectroscopy has been performed to investigate the effects of the electric field on 0.68PbMg1/3Nb2/3O3–0.32PbTiO3 (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 E1 and completed at higher field E2. In the intermediate field range from E1 to 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.
