description: The given work is devoted to investigation of the influence of an external electric field on the low-frequency relaxation dynamics of PMN ceramics and comparison with the behavior of a single crystal. The effect of an external electric field on the dielectric properties of PMN ceramics at 242 K and 246 K and a PMN single crystal (111) at 242 K in the frequency range of 0.01 Hz - 10 kHz was studied by broadband dielectric spectroscopy. The magnitude of the applied field is from 0 to 6 kV/cm. The obtained dielectric spectra were analyzed using the Cole-Cole model function. The approximation was implemented using the ProFit application program. The field dependences of the parameters of the relaxation process are obtained. A tightening of the relaxation time spectrum and a decrease in the dielectric strength of the process with an increase in the external electric field were found. The relaxation parameters of ceramics and single crystal are compared. It was found out that at 242 K and 246 K and external fields up to 6 kV/cm, PMN ceramics does not have a transition to the ferroelectric phase.
