Abstract
We determined oscillatory periods, phases, and coupling strengths for [001] Fe/V and Fe/Cr, using a highly accurate, non-self-consistent first-principles method. The periods obtained for Fe/Cr are consistent with experiment both for paramagnetic and antiferromagnetic Cr. These results clearly show how the Cr antiferromagnetism affects the exchange coupling. For [001] Fe/V, we predict short and long periods that have not yet been observed, but provide tests for the theory. We also discuss the merits of our computational approach.

Layered Magnetic Structures: Evidence for Antiferromagnetic Coupling of Fe Layers across Cr Interlayers
We investigated exchange coupling of Fe layers across Au and Cr interlayers by means of light scattering from spin waves. For Au interlayers we find a continuous decrease of thi...
