The electrical properties of [001]-oriented morphotropic phase boundary (1-x)Pb(Mg_(1/3)Nb_(2/3))O_3-xPbTiO_3 (PMN-33%PT) single crystal have investigated as a function of temperature and frequency. The ac-conductivity exhibited continuous dispersion at all temperatures and frequency range examined and was associated to the thermally activated space charge carriers and local off-centering of Ti~(4+) and Pb~(2+) ions. The variations in ferroelectric phase transition temperatures observed in the poled state were associated to the polarization fluctuations and phase co-existence.
