Abstract:
The magnetic and resonance properties of the DyMn$_{2}$O$_{5}$–Mn$_{3}$O$_{4}$ nanoparticle composite have been experimentally investigated. Two magnetic transitions at temperatures of $T_{1}\approx$ 65 K and $T_{2}\approx$ 230 K have been established; the $T_1$ value differs from the temperatures of the transitions in the initial materials, which has been attributed to the interparticle interactions. Temperature $T_2$ corresponds to the DyMnO$_3$ impurity phase (1 at.%). Three microwave absorption peaks have been observed in the magnetic resonance spectrum, which is explained within the model of a magnetically two-phase system. One resonance is attributed to Mn$_3$O$_4$, and the other two peaks are attributed to an ensemble of highly anisotropic DyMn$_{2}$O$_{5}$ particles with a random distribution of anisotropy axes.
