Temperature dependent electronic transport in concentrated solid solutions of the 3d-transition metals Ni, Fe, Co and Cr from first principles.

An approach to the calculation of transport coefficients is applied to the calculation of transport properties of fcc alloys of Ni, Fe, Co, Cr. The coherent potential approximation used to treat chemical disorder, temperature induced magnetic moment fluctuations and lattice vibrations via the alloy analogy. For the nonmagnetic alloys, Ni20Cr, and NiCoCr the combined effects of chemical disorder and lattice vibrations result in a monotonic increase in the resistivity as a function of temperature from an already large residual resistivity. For magnetic NiCo, NiFe, NiFeCo, additional electron scattering from magnetic fluctuations results in a rapid increase of the resistivity with temperature.The electronic part of the thermal conductivity in Ni20Cr, and NiCoCr, monotonically increases with temperature. In the magnetic alloys, electron scattering from magnetic fluctuations leads to an initial rapid decrease in thermal conductivity until this is overcome by an increasing number of carriers.
