The antiferromagnetic defect scattering from an 80 at.% gamma -MnZn alloy was measured at 4.2K using neutron polarisation analysis. The magnetic defect was found to extend to second nearest neighbours from the impurity site which carries no moment to within +or-0.1 mu <sub>B</sub>. The authors calculate d mu /dC=-2.8 mu <sub>B</sub> per atom which is in good agreement with the value derived from the variation of magnetic Bragg scattering with composition. They have also shown that Zn atoms anticluster in gamma -Mn.
