Theoretical modeling of the magnetic properties of Fe3O4-Fe3-xTixO4 composites obtained by the sol-gel method with subsequent hydrothermal treatment has been carried out. The magnetization reversal fields and the number of particles in different magnetic states of an ensemble of two-phase particles with an infinitely thin boundary between the phases and a characteristic size varying in the range from 30 to 80 nm were calculated using the "magnetic rectangles" method. Hysteresis characteristics of an ensemble of chemically inhomogeneous magnetostatically interacting particles were obtained, consistent with experimental data. Keywords: Composites, magnetic granulometry, micromagnetism, two-phase particles, magnetostatic interaction.
