We have studied the temperature dependences of the magnetic susceptibility and the electron magnetic resonance in Pr1–xSr x MnO3/YSZ polycrystalline films (x = 0.2, 0.4). The paramagnetic properties of samples indicate the presence of short-range-order ferromagnetic correlations above the phase transition temperature (T c ). The existence region of such correlations has been considered using the Griffith theory.
