First-principles scattering matrices for spin-transport
K. Xia, M. Zwierzycki, M. Talanana +2
Details are presented of an efficient formalism for calculating transmission and reflection matrices from first principles in layered materials. Within the framework of spin densit…
Conductance calculations for quantum wires and interfaces: mode matching and Green functions
P. A. Khomyakov, G. Brocks, V. Karpan +2
Landauer's formula relates the conductance of a quantum wire or interface to transmission probabilities. Total transmission probabilities are frequently calculated using Green func…
Spin-injection through an Fe/InAs Interface
M. Zwierzycki, K. Xia, P. J. Kelly +2
The spin-dependence of the interface resistance between ferromagnetic Fe and InAs is calculated from first-principles for specular and disordered (001) interfaces. Because of the s…
Spin-dependent Transparency of Ferromagnet/Superconductor Interfaces
K. Xia, P. J. Kelly, G. E. W. Bauer +1
Because the physical interpretation of the spin-polarization of a ferromagnet determined by point-contact Andreev reflection (PCAR) is non-trivial, we have carried out parameter-fr…
Spin Torques in Ferromagnetic/Normal Metal Structures
K. Xia, P. J. Kelly, G. E. W. Bauer +2
Recent theories of spin-current-induced magnetization reversal are formulated in terms of a spin-mixing conductance . We evaluate from first-principles for a num…
Interface resistance of disordered magnetic multilayers
K. Xia, P. J. Kelly, G. E. W. Bauer +3
We study the effect of interface disorder on the spin-dependent interface resistances of Co/Cu, Fe/Cr and Au/Ag multilayers using a newly developed method for calculating transmiss…
