The Raman scattering experiment in several optical geometries below 400 cm−1 was carried out in the poled sample of the 0.8Pb(Zn 1/3 Nb 2/3 )O 3 -0.2PbTiO 3 (PZN-20%PT) crystal. Raman modes in the low frequency region were assigned. It was concluded that the low frequency Raman modes in PZN-20%PT are mainly due to a polar distortion of the paraelectric cubic Pm m structure. The Raman scattering was found to be sensitive to the inhomogeneous ferroelectric distortion or existence of the polar nano-region in the cubic phase of the PZN-type relaxor. Both the E(TO1) and A 1 (TO1) modes, corresponding to the soft modes in the tetragonal phase of PbTiO 3 , do not at all depend on temperature near the ferroelectric phase transition point in PZN-20%PT.
