Thermal conductivity and electrical resistivity of solid iron at Earth's core conditions from first-principles [PDF]

open access: greenPhys. Rev. Lett. 121, 096601 (2018), 2017
We compute the thermal conductivity and electrical resistivity of solid hcp Fe to pressures and temperatures of Earth's core. We find significant contributions from electron-electron scattering, usually neglected at high temperatures in transition metals.
