A Mn-55 nuclear magnetic resonance study of a layered perovskite La1.4Sr1.6Mn2O7 is reported. Between 4.2 K and the magnetic ordering temperature, 100 K, zero field spin echo spectra consist of signals corresponding to the double-exchange (DE) states and charge localized Mn3+, Mn4+ states. This indicates occurrence of electronic and magnetic phase segregation into ferromagnetic metallic and ferromagnetic insulating regions. Above 100 K a DE line is observed, revealing the presence of long lived metallic clusters. The relation of results to magnetoresistive properties of the compound is discussed. (C) 2003 Elsevier B.V.
