Implication

Computational modeling demonstrates residual resistivity mechanisms in dilute ternary alloys, confirming two-current transport behavior in ferromagnetic hosts.

Key Points

To calculate residual resistivity and investigate deviations from Matthiessen's rule in nonmagnetic and ferromagnetic dilute ternary alloys using ab initio electronic structure methods.
Applied density functional theory using the Korringa-Kohn-Rostoker Green's-function method to calculate self-consistent impurity scattering with one perturbed host potential shell.
Evaluated transport quasiclassically via the Boltzmann equation, modeling noninteracting simple-metal (4sp, 5sp) and transition-metal (3d, 4d) impurities.
Employed a two-current model to account for spin-dependent electron transport in ferromagnetic nickel host systems compared with nonmagnetic copper hosts.
Confirmed the validity of Matthiessen's rule in nonmagnetic copper-based ternary alloys, showing satisfactory agreement with experimental data.
Demonstrated the accuracy of the two-current model for characterizing residual resistivity in ferromagnetic nickel-based ternary systems.
