(formula presented) NMR investigation of (formula presented) (formula presented)

(formula presented) nuclear magnetic resonance (NMR) in (formula presented) (formula presented) manganites provides local evidence of the magnetic inhomogeneities arising from the electronic structure changes below (formula presented) The temperature dependences of magnetization, resistivity, and NMR spectra were compared in samples in the ferromagnetic insulating, ferromagnetic metallic, and charge-ordered phases. Spin-spin relaxation enhancement around 15 K is attributed to a critical slowing down of the Nd sublattice. © 2002 The American Physical Society.
