Temperature dependence of the resistivity and impurity susceptibility in the infinite-U Anderson dilute alloy model
In this paper we consider the limit U -> infinity of the Anderson dilute magnetic alloy Hamiltonian. The impurity susceptibility and residual resistivity are shown to depend in a simple manner on the impurity electron occupation number <nd>. No assumptions are made about the parameters of t...

| Achoimre: | In this paper we consider the limit U -> infinity of the Anderson dilute magnetic alloy Hamiltonian. The impurity susceptibility and residual resistivity are shown to depend in a simple manner on the impurity electron occupation number <nd>. No assumptions are made about the parameters of the model and we develop an integral equation for <n d>. This integral equation is numerically solved and a table of self consistently determined values of <nd> presented. Results are also given for the impurity susceptibility and residual resistivity. |
