description: As a result of the research, hysteresis loops were measured for the material 0.8Pb(Mg1/3Nb2/3)O3 0.2PbTiO3 (PMN-20PT) in the temperature range from 130 K to 295 K at different frequencies. Probably the data presented for this material and this temperature range is the most detailed at the moment. A new method was proposed for the three percentiles E10, Ec, E80âfields at which 10%, 50%, and 80% of the crystal are switched, respectively, which makes it possible to characterize the ferroelectric hysteresis loops in more detail. The nonlinear dependence of the coercive field on temperature, which was described earlier is confirmed. Using the developed method, it is shown that the dependence of the parameters of the ferroelectric hysteresis loops in a PMN-20PT single crystal depends in a complex way on the frequency. During data processing, the Matlab application program was used with a unique code that allows you to quickly process large amounts of data. When compiling a literature review, information was searched in global computer networks.
