Abstract
The polarization of magnetic impurities by a spin-density-wave tends to stabilize the commensurate SDW phase and to modify the coordinates of the tricritical point. A numerical calculation has been performed to obtain the impurity concentration dependence of the tricritical point coordinates and the associated discontinuity in the SDW wave-vector.
