Calculating scattering matrices by wave function matching on Co-Cu interfaces

In this paper the spin-dependent transmission through an ideal copper-cobalt interface is calculated using the method of wavefunction matching (WFM) implemented with a basis of muffin-tin orbitals (MTO) within the framework of density functional theory (DFT). A sketch of DFT is given and the theory of muffin-tin orbitals is explained, illustrated with examples of vanadium, copper and cobalt bands structures.
