The average magnetic moments of Mn atoms dissolved in fcc Ni -Co alloys havebeen determined as a ftmction of concentration of host alloys. The measurementswere made with alloys containing 2 atomic percent Mn at about 300 K and 100 Kby means of diffuse scattering of polarized neutrons. The average magneticmoment of Mn, which is about 3 tts in t>ure Ni, decreases with increasinu Coconcentration and changes its direction at about 50 atomic percent Co fromparallel to antiparallel to the bulk magnetization of host alloys. This behavioragrees qualitatively with the theoretical results obtained under the assumption ofthe extended coherent potential approximation, but a quantitative discrepancy isfound especially near Co concentration of about 20 to 40 atomic percent.
