We have calculated the lattice contribution to the electrical resistivity of body-centered-cubic iron at ambient pressure and two temperatures, 300 K and 500 K, using density functional theory and the Kubo-Greenwood formula.

Abstract

We have calculated the lattice contribution to the electrical resistivity of body-centered-cubic iron at ambient pressure and two temperatures, 300 K and 500 K, using density functional theory and the Kubo-Greenwood formula. We performed extensive size and k-point sampling tests by including up to 1024-atom cells and up to 10 k points. The calculated resistivities fall within the range of the experimental estimates at 500 K, and overestimate it by only similar to 5% at 300 K.
