• Field-induced conduction electron spin polarization is investigated in the Anderson model on the basis of the Yamada-Yosida theory. In the case of electron hole symmetry the spin polarization at a distance r from an impurity is expressed by (χH/gμ_B)cos 2k_Fr/4πr^3 for r>r_0=4πE_Fχ_<even>/k_F(gμ_B)^2, where χ_<even> denotes the even part of the susceptibility χ with respect to electron correlation U. On the same lines, the interaction energy between two impurities is calculated.
