description: In this work, the aging processes and kinetics of phase switching when applying an external field were studied in a single crystal of a model ferroelectric, a lead magnoniobate relaxor PbMg1/3Nb2/3O3 (PMN). PMN has high values of permittivity and piezoceramic properties in a wide temperature range, which leads to its wide practical application. The studies were carried out in a wide frequency range (10-4Hz - 10MHz) and in the temperature range (150-300K) using broadband dielectric spectroscopy. The aging processes in PMN were investigated in the area of the maximum of permittivity, and changes of loss spectrum during aging were analyzed. It has been discovered that there is a frequency maximum of aging, which can be found on the left wing of loss spectrum maximum. Scaling relations for aging PMN were also obtained in the temperature range of the maximum permittivity. In addition, phase transitions were studied in external electric fields at fixed temperatures: T1 = 246K and T2 = 220K. We managed to obtain a positive capacitance-voltage effect when applying an external field at 246K in the amount of 41% from the initial value for permittivity. Updated E-T PMN phase diagram.
