摘要：

The electronic and magnetic structures are calculated for the Ni/Fe(001) overlayer system within the local-density approximation using the tight-binding linear muffin-tin orbital method in the atomic sphere approximation. Magnetic moment calculations of Ni/Fe-n/Ni for n=(1, 3,5,7,9, 11) monolayers (ML) show that the coupling at the interface is ferromagnetic. The average value of the Fe magnetic moment is slightly enhanced as compared to its bulk value, and bulk Fe can be represented by at least 9 ML. (C) 2002 Elsevier Science B.V. All rights reserved.
