On the interpretation of NMR experiments in CoGa alloys

We show that in Co_xGa_1?x alloys NMR data reported by Grover et al. in combination with existing magnetization data can be interpreted as follows. The group of atoms consisting of a Co antistructure atom and its eight nearest neighbours behaves as a magnetic entity. The (saturation) magnetic moment of the anti-structure atom (?1.6μ_B) is much larger than the corresponding moment on a neighbouring Co atom (?0.16 μ_B).
