Description
Summary:-The magnetic properties of Fe.sub.3O.sub.4-Fe.sub.3 -.sub.xTi.sub.xO.sub.4 composites synthesized by various methods were simulated based 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 of chemically heterogeneous two-phase particles. It is shown that the used approach is also applicable to the samples consisting mainly of superparamagnetic particles in which the saturation remanent magnetization is provided by the particles blocked due to the magnetostatic interaction.
