This paper presents the results of modelling of both magnetic and magnetostrictive properties of high permeability Mn0.51Zn0.44Fe2.05O4 ferrites. The parameters of energy-based Jiles-Atherton-Sablik (J-A-S) model were calculated for each experimental hysteresis loop on the basis of evolutionary strategies and Hook-Jevis optimization method. Finally, high conformity between experimental and modelling results was achieved. This high conformity indicates that the presented results create new opportunity of modelling of the properties of inductive components based on ferrites as well as quantitative description of magnetization process.
