Abstract:

A many-band conductivity model has been derived and applied to analyze the concentration dependence of the electrical residual resistivity (RR) of several actinides based disordered alloys. It was qualitatively shown that equal probabilities of s -> d and s -> f transitions of scattered conductivity electrons lead to the deviations from Nordgeim's rule observed in these alloys. Numerical evaluation of RR of neptunium, plutonium, americium, and curium based alloys was made within the coherent potential approximation (CPA) derived for the many-band conductivity model. Numerical calculations were made using ab initio obtained bcc-Np and fcc-Pu, Am, and Cm densities of states, as the starting point for the iterative CPA procedure. The results of the RR modeling were compared with available experimental data and allow us to conclude that the proposed model offers promising opportunities to investigate RR of similar classes of alloys.
