• The effect of both the Spin interaction between impurities and conduction electrons on the spin density wave (SDW) is studied on the basis of a simple-band model. The impurity spin is treated as a classical spin In the spin. In the case of the SDW containing one impurity the energy and, For a finite concentration the Neel temperature, T_N, and the order parameter at absolute ziro, Δ(0), are calculated by applying the Abrikosov-Gorikosov-Gorkov the theory of superconductivity. It is found that the impurities have two effects: depairing effect similar to the in superconductivity and pairing effect arising from the antiferromagnetic alignment of the impurity spins that follows the SDW polarization of these effects affects the behavior of T_N and Δ(0). Calculated results can be compared qualitatively with experimental data on Cr-Fe and Cr-Co alloys.
