Host NMR in dilute magnetic alloys: the spatial variation of the spin polarization

The Hartree-Fock theory of the spatial dependence of the spin polarization in dilute alloys is developed in both cases of a 'magnetic' and 'nonmagnetic' impurity. It is shown that, in the latter case, the spin polarization should be reduced with respect to the asymptotic limit at rather large distances r of the impurity, such as k F r
