Current induced spin flip scattering at interfaces in noncollinear magnetic multilayers
Peter M Levy, Jianwei Zhang
We show that when one drives a charge current across noncollinear magnetic layers the two electron Coulomb scattering creates a spin flip potential at interfaces. This scattering i…
The steady state in noncollinear magnetic multilayers
Jianwei Zhang, Peter M Levy
There are at least two different putative steady state solutions for current across noncollinear magnetic multilayers; one has a discontinuity in the spin current at the interface…
Different steady states for spin currents in noncollinear multilayers
Peter M Levy, Jianwei Zhang
We find there are at least two different steady states for transport across noncollinear magnetic multilayers. In the conventional one there is a discontinuity in the spin current…
Identification of transverse spin currents in noncollinear magnetic structures
Jianwei Zhang, Peter M Levy, Shufeng Zhang +1
We show that the transverse components of spin current in a ferromagnet is linked to an off diagonal spin component of the transmission matrix at interfaces;it has little to do wit…
A self-consistent treatment of non-equilibrium spin torques in magnetic multilayers
Asya Shpiro, Peter M. Levy, Shufeng Zhang
It is known that the transfer of spin angular momenta between current carriers and local moments occurs near the interface of magnetic layers when their moments are non-collinear.…
A proper ballistic calculation of tunneling conductance for real junctions
P. M. Levy, K. Wang, P. H. Dederichs +4
Employing an ab initio Screened Korringa-Kohn-Rostoker (SKKR) band structure method for a metal-vacuum-metal junction, we find that the tunnel conductance is different when it is c…
