The paper presents the results of the experimental studies of magnetic and resonance properties of the DyMn2O5 – Mn3O4 particles composite. There are two magnetic transitions at temperatures T1 65 K and T2 230 K. T1 differs from the transition temperatures for the initial materials, and this fact is associated with the interparticle interaction. T2 corresponds to the impurity phase DyMnO3 (1 at.%). Three peaks of microwave absorption are observed in the magnetic resonance spectrum, which is explained in the framework of the model of a two-phase system in magnetic relation. One resonance is attributed to Mn3O4 and the other two peaks refer to the ensemble of strongly anisotropic DyMn2O5 particles with a random distribution of anisotropy axes.
