Brillouin and angular dependent Raman scattering studies on relaxor ferroelectric 0.83Pb(Mg1/3Nb2/3)O3-0.17PbTiO3 single crystals

ORAL

Abstract

The relaxor ferroelectrics (RFs) are characterized by their nanometric local region so called polar nanoregions (PNRs) and chemical ordered regions (CORs) [1,2]. In the present study, the temperature and angular dependences of Raman scattering were studied to investigate the local properties in 0.17Pb(Mg1/3Nb2/3)O3-0.83PbTiO3 (PMN-17PT) single crystals with intermediate random fields. The existence of CORs with Fm m and PNRs with R3m symmetry in a cubic phase was shown by the angular dependence of VV and VH Raman scattering spectra. In the temperature dependence of broadband Brillouin scattering, the stretched slowing down mechanism of PNRs towards the Curie temperature was observed in a cubic phase [3]. These results are compared with PMN-56PT with weak random fields.
