This work presents the results of the experimental studies of the magnetic resonance properties of the Y$_{0.5}$Sr$_{0.5}$Cr$_{0.5}$Mn$_{0.5}$O$_3$ polycrystalline system. We found that two absorption lines are observed in the magnetic ordering region at $T$ 80 K in the spectrum. When changing to the paramagnetic region, one of the lines disappears, but a set of weak lines appears, which are identified as belonging to the Mn$^{2+}$ impurity ions. The temperature behavior of the main peak line width is analyzed within the framework of the single-ion relaxation theory. Mn$^{3+}$ ions were found to be responsible for the low-temperature peak, and Cr$^{4+}$ ions are responsible for the high-temperature peak. The constants of the molecular fields acting on the Mn$^{3+}$ and Cr$^{4+}$ subsystems have been determined.
Keywords: yttrium-strontium chromite-manganite, magnetic resonance, one ionic relaxation.
Mots-clés : antiferromagnetic interaction
