- 論文の詳細を見る
We have investigated the indirect exchange coupling between Co and Gd across nonmagnetic interlayers in Co/X/Gd/X multilayers (X=Ag, Au and W). The strength of the coupling J_<Co-Gd> decreases with increasing the interlayer thickness t_X for all Xs. However, the manner of the decrease depends strongly on X : J_<Co-Gd> decreases slowly for X=Ag and Au, and the coupling remains even for t_X≥10Å. On the other hand, J_<Co-Gd> shows a drastic decrease for X=W, and the coupling disappears for t_X≥5Å. The origin for the difference is attributable to the electronic structures of interlayers.CoGdinterlayersindirect exchange couplingmultilayers
