摘要：

A theory for the magnetic form factor in Kondo systems is presented which allows us to distinguish Kondo reduction of the moments from conduction electron polarization effects. The sign of the deviations of the form factor at small scattering vector is ascribed to the dominance of a superexchange-like contribution to the conduction electron polarization, which is contained in the Anderson model in addition to the usual RKKY polarization.
