The nuclear magnetic resonance of iron group element alloyed with Palladium has been studied with special emphasis on on dilute ferromagnetism and the giant moment problem. This paper repoorts on the NMR of Co^<59> in dilute ferromagnetic Co-Pd alloys and gives a simple interpretation of these results, The resonance frequency of Co-^<59> in these alloys was about 216 Mc at liquid helium temperature, nearly the same as that in pure fcc cobalt, 217.2 Mc at 0°K. This suggests that the magnetic moment on Co atom is roughly equal to that in pure cobalt metal. By use of these results the range of the magnetic interaction of Co atoms in these alloys is roughly estimated using simple probability arguments. The giant moment is constructed from the sum of the moment of the Co atom and the moments of Pd atoms within an interaction "distance" from the Co atom.
