Abstract
Electron spin resonance spectra of La0.05Pb0.5MnO3 and La1.34Sn0.66Mn2O7 po wder samples have been investigated in the temperature range, 120-500 K. Th e spectra exhibit a gradual narrowing of the ferromagnetic resonance signal , upon increasing the temperature and approaching Curie temperature, Tc. Th e temperature dependence of the linewidth and the double integrated resonan ce intensity are attributed to ferromagnetic inhomogeneities. (C) 1999 Else vier Science B.V. All rights reserved.
