Structural and electron magnetic resonance studies in a broad temperature range are reported for Pr0.6Sr0.4MnO3 manganite synthesized by sol-gel method. Temperature dependence of magnetic resonance spectra is analyzed in the paramagnetic state and compared to similar systems. Using the temperature variation of signal intensity the activation energy is calculated.
