We report on an Mn-55 NMR investigation of calcium-doped manganite samples carried out at 4.2K. In the insulating members of the family. the localization or hole-rich Ferromagnetic clusters is revealed by the peculiar two-peaked spectra, and by distinct shifts of the resonance lines in an external field. Results are discussed in view of inelastic neutron scattering findings and combined La-139 NMR and pSR data.
