Residual resistivity of n-d impurities diluted in noble hosts

摘要

We discuss the temperature-independent resistivity of nd (n = 3,4) transition metal impurities diluted in Cu host, using a T-matrix formulation in a single band system. We take into account the translational symmetry breaking introduced by the impurity and therefore a non-local charge potential is obtained. The effect of volume difference between impurity and host elements is also considered in the calculation. Our numerical results describe quite well the available experimental data.
