Abstract:

The Anderson model for dilute magnetic alloys is studied in the renormalized random phase approximation which has recently been applied to the Wolff model by Suhl and his co-workers. The resulting integral equations are solved approximately with a suitable trial function which becomes asymptotically self-consistent in the limit U / πΔ→∞, where U is the Coulomb interaction and Δ the d-level width. The solution is proved to give incorrect temperature dependence of the resistivity and the zero-frequency susceptibility in comparison with the rigorous results obtained by other methods.
