Effect of the Phase Factor of the Reflection Amplitude on the Interlayer Exchange Coupling in (001) Co/Cu/Co Multilayers
Journal of Magnetics, Volume 6, Number 2, 30 Jun 2001, Pages 43-46
Abstract
The reflection-amplitude approximation is used to calculate the interlayer exchange coupling in (001) Co/Cu/Co multilayers. The dependence of the phase factor of the reflection amplitude on the energy and wave vector is included. The contribution of each period is calculated and the results are compared with those from asymptotic behavior. It is shown that the energy and wave-vector dependence of the phase factor may affect the interlayer exchange coupling significantly.
