Two types of experiments were carried out to verify the proposed method. One is to measure the Raman spectra for a fixed grain in the PLZT ferroelectric sample before and after 90 rotation. The other is to observe variations of Raman spectra for a fixed grain under a DC field. The results revealed that by a 90 rotation the Raman spectra for grains in an in-plane polarized sample vary and the Raman spectra for grains in both un-poled and out-plane polarized samples remain unchanged. The results also indicated that the in situ Raman spectrum varies as the magnitude of the applied DC field increases. These results showed that the domain switching will leads to variations of Raman spectrum.
