摘要：

The amplitude and phase of a.c. electric response of single crystals of Pb(Mg1/3Nb2/3)O-3 relaxor ferroelectrics on sinusoidally modulated thermal flux in the wide range of modulation frequencies have been investigated without and under application of external electric field. The contribution to the response observed under application of electric voltage concerned with the strong temperature dependence of dielectric permittivity and the role of electron states in the volume and near-surface layer of structure disordered ferroelectrics with diffuse phase transition is discussed.
