The low frequency measurements of linear and nonlinear components of complex dielectric permittivity() were carried out on lead magnoniobate(PMN) single crystals in the wide temperature region (100-450K). It has been shown that the application of a DC field (DCF) to a PMN crystal produces essential different results depending on the DCF direction. Some additional peculiarities appear on the ∊(T) dependences when a DCF is applied in <111> direction at values E≥E ~1.5 kV/cm. Such behavior may be explained in terms of the origin of ferroelectrical ordering in low temperature region induced by a DCF. The neutron scattering experiments confirm this supposition. For the first time nonlinear dielectric data were used to construct the E-T phase diagram (PD).
