Single crystals of La 0.9 Sr 0.1 MnO 3 and La 0.8 Sr 0.2 MnO 3 manganites are examined using magnetic resonance in the temperature range 80–370 K. It is found that magnetostatic oscillations arise near the Curie temperature. The possible reasons for the appearance of additional lines in the ferromagnetic resonance (FMR) spectrum are considered, and the anisotropy field and the type of crystalline magnetic anisotropy in the La 0.8 Sr 0.2 MnO 3 compound are determined. It is shown that the crystalline magnetic anisotropy in the La 0.9 Sr 0.1 MnO 3 compound exhibits specific features associated with its type of crystal structure.
