Magnetic susceptibility measurements on Cr .V.Co alloys containing 1 at % Cohave been made in the range of x from zero to 1 over the temperature range 4.2 to 660K. The susceptibility due to Co impurities above the Neel temperature follows Curie-Weiss law. The magnitude of the effective moment, about 3 jt. in CrCo alloy, decreasesmonotonically with the increase of x, and the localized moment disappears in .x=0.3alloy. From the results of magnetic susceptibility and NMR measurements, it isconcluded that the coexistence of magnetic and nonmagnetic Co atoms, at least forx=O.2 and 0.25 alloys, exists and that the formation of localized moment seems todepend on the configuration not only of nearest neighbors but also of long range.
