Abstract

Fe layer thickness dependence of the interlayer exchange coupling across a Au spacer is investigated for MBE-grown Au/Fe/Au/Fe/Au(001) films involving two step-shaped Fe layers with each step 1 ML high. The coupling strength oscillates as a function of each Fe layer thickness with a 2 ML Fe period, which is attributed to the resonance state involving the Fe majority spin band. The interlayer coupling is also studied for Fe/Si and Fe/FeSi multilayers as functions of semiconducting spacer thickness and temperature.
