This work presents the results of the experimental studies of the magnetic resonance properties of the Y0.5Sr0.5Cr0.5Mn0.5O3 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 Mn2+ impurity ions. The temperature behavior of the main peak line width is analyzed within the framework of the single-ion relaxation theory. Mn3+ ions were found to be responsible for the low-temperature peak, and Cr4+ ions are responsible for the high-temperature peak. The constants of the molecular fields acting on the Mn3+ and Cr4+ subsystems have been determined.
