Electron magnetic resonance measurements were employed for studying the magnetic spin structure in bulk and crushed crystalline samples of doped (formula presented) and (formula presented) and self-doped (formula presented) grown by fused-salt electrolysis. The ferromagnetic resonance exhibits a common characteristic multiline spectrum for single crystals and “noiselike” oscillations superimposed on ferromagnetic signal for crushed crystals. A coexistence of ferromagnetic and electron paramagnetic resonance signals was observed in a wide temperature range around (formula presented) The results obtained are discussed regarding the presence of inherent magnetic inhomogeneities in studied manganites.
