Abstract

Polarized micro-Raman spectroscopy was carried out on the (001) face of a0.67PbMg_1/3Nb_2/3O₃-33%PbTiO ₃(PMN-33%PT) single crystal. The Raman images revealed the spatial variations ofthe intensity of the Raman bands, suggesting that the structure in the PMN-33%PTsingle crystal varied from one micro-area to another. When changing thepolarization direction of the incident light with respect to the selectedcrystalline axes, the intensities of the Raman modes varied periodically.According to the Raman selection rules (RSRs), the angular dependences of theRaman modes indicated that the PMN-33%PT single crystal is in the monoclinicphase. Furthermore, the color patterns in the Raman images were associated withthe coexistence of the M_A- and M_C-type monoclinic phasesin the PMN-33%PT single crystal. Our results provide useful information forunderstanding the microheterogeneity of the relaxor PMN-xPT single crystals withcompositions near the morphotropic phase boundary region.
