N2 - Electron spin resonance spectra of La0.5Pb0.5MnO3 and La1.34Sn0.66Mn2O7 powder samples have been investigated in the temperature range, 120-500 K. The spectra exhibit a gradual narrowing of the ferromagnetic resonance signal, upon increasing the temperature and approaching Curie temperature, Tc. The temperature dependence of the linewidth and the double integrated resonance intensity are attributed to ferromagnetic inhomogeneities.
