Investigation of phase coexistence, morphotropic phase boundaries, and ferroelectric domain structures by scanning Raman spectroscopy and piezoresponse force microscopy.

Micro-Raman study of a relaxor ferroelectric PMN-0.32PT
Description
Micro-Raman study of a relaxor ferroelectric PMN-0.32PT single crystal.
(a) Cross-polarized Raman spectrum of a PMN-0.32PT single crystal taken from two different spots of the sample revealing a different symmetry.
(b) Map of the intensity ratio of the cross-polarized Raman scattering at 780 and 270 cm-1 shows the regions with different symmetry have a stripe pattern.
