    Abstract The magnetostatic and magnetic resonance properties of the Y0.5Sr0.5Cr0.5Mn0.5O3 polycrystalline system have been experimentally studied. The intracrystalline ferromagnetic interaction turned out to be prevalent while the intercrystalline interaction appears to have antiferromagnetic character. We found that two absorption lines are observed in the spectrum in the magnetic ordering region at T < 80 K. The high-field line corresponds to the interacting parts of polycrystal related to the disordered shells and the low-field peak is system of ferromagnetic particles.

    The magnetostatic and magnetic resonance properties of the Y0.5Sr0.5Cr0.5Mn0.5O3 polycrystalline system have been experimentally investigated. The predominance of the intracrystalline ferromagnetic interaction and the antiferromagnetic character of the intercrystallite interaction have been established. The magnetic resonance spectrum in the magnetically ordered region consists of two lines. The high-field line corresponds to the interacting parts of polycrystal shells and the low-field peak is related to the disordered system of ferromagnetic particles.

    Abstract The magnetic and resonance properties of the DyMn2O5–Mn3O4 nanoparticle composite have been experimentally investigated. Two magnetic transitions at temperatures of T1 ≈ 65 K and T2 ≈ 230 K have been established; the T1 value differs from the temperatures of the transitions in the initial materials, which has been attributed to the interparticle interactions. Temperature T2 corresponds to the DyMnO3 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 Mn3O4, and the other two peaks are attributed to an ensemble of highly anisotropic DyMn2O5 particles with a random distribution of anisotropy axes.
