Resumen:
We report magnetization and electron-spin-resonance (ESR) measurements around the Curie temperature on single-crystal and ceramic colossal magnetoresistance manganites. The temperature dependence of the ESR linewidth below ≈1.1TC is well described in terms of a two-magnon scattering relaxation mechanism induced by the demagnetization fields of the pores between crystallites.
