Application of the Landauer formalism to the calculation of spin current
Valentin Fadeev, Andrey Umerski
In this communication we apply the Landauer method and transfer matrix formalism to the calculation of spin current in magnetic multilayered structures within a ballistic quantum-m…
Topological phase of the interlayer exchange coupling with application to magnetic switching
A. Umerski
We show, theoretically, that the phase of the interlayer exchange coupling (IEC) undergoes a topological change of approximately as the chemical potential of the ferromagnetic…
Magnetic anisotropy of vicinal (001) fcc Co films: role of crystal splitting and structure relaxation in step-decoration effect
M. Cinal, A. Umerski
The uniaxial in-plane magnetic anisotropy (UIP-MA) constant is calculated for a single step on the (001) surface of fcc Co() films. The calculations are done for both an undecor…
A selfconsistent theory of current-induced switching of magnetization
D. M. Edwards, F. Federici, J. Mathon +1
A selfconsistent theory of the current-induced switching of magnetization using nonequilibrium Keldysh formalism is developed for a junction of two ferromagnets separated by a nonm…
