Abstract :
Magnetoresonance features of strontium-doped lanthanum manganites-perovskites in microwave band were investigated. One wide resonance peak has been observed for sintered bulk specimen. For thin-films specimens two resonance peaks has been detected. This fact shows that in thin-film specimens a few magnetic subsystems present. One of them has a low magnetization of saturation magnitude and corresponds to asperomagnetic magnetic state in our view. Other peak corresponds to typical ferromagnetic state apparently.
