A satellite line shifted in the direction to lower internal fields as compared with the main line has been observed in the NMR spectrum of 63 Cu in CuMn alloys diluted to 0.5 or 2.5 at% Mn. The shift of the satellite is independent of the Mn concentration but varies with the applied field and the temperature as H / T . This indicates that the satellite is due to the spin density perturbation around the localized magnetic moment. The experimental data suggest that the satellite originates most probably from the 63 Cu nuclei on the first coordination shell of the Mn atoms. The NMR spectrum of the same nuclei shows no second order quadrupole effect within the experimental error.
