Abstract: The work presents enhanced, relatively new iterative method for obtaining the classical Preisach distribution from a single, saturated hysteresis loop. As the material for research and analysis, the ceramic solid solution (1-x)Pb(Mg1/3Nb2/3)O 3-xPbTiO3 (x = 0 to 0.40) was selected. Distributions were obtained for (1-x)PMN-xPT ceramics as a function of PT content, and function of temperature, for a selected composition from the morphotropic phase boundary region. The paper also proposes a mathematical model of the Preisach distribution and the parameters of the distribution were calculated. The typical factors achievable directly from the hysteresis loop with a coefficients determined from the analytical Preisach model were compared.
