摘要：

Exchange couplings in (001) fee Co/Cu/Co multilayers with various thicknesses of the Co layer are examined in a realistic tight-binding model. Many sharp features (known as Fano resonances) id the reflection amplitude as a function of energy are found, which do not exist in a one-band model. With a simplified two-band tight-binding model, the effects of Fano resonances can be calculated accurately, and they are found to play an important role in determining the magnetic-layer thickness dependence of the interlayer coupling.
