N2 - The magnetic properties of Fe3O4–Fe3 – xTixO4 composites synthesized by various methods were simulatedbased on the model of an ensemble of magnetostatically interacting particles. The results are in good agreement with the hysteresis characteristics of the samples calculated earlier in the framework of the model ofchemically heterogeneous two-phase particles. It is shown that the used approach is also applicable to thesamples consisting mainly of superparamagnetic particles in which the saturation remanent magnetization isprovided by the particles blocked due to the magnetostatic interaction.
