White Data Storage Systems Center, Carnegie Mellon University, Pittsburgh, Pennsylvania 15213 Received 11 February 2000 We have investigated the interlayer exchange coupling between two ferromagnetic (FM) layers mediated by an antiferromagnetic (AF) layer. We have extended Slonczewski's "proximity magnetism" idea in the trilayers by including an AF magnetocrystalline anisotropy and considering interfacial exchange coupling that is influenced by the interface roughness. Using a continuum model we obtain the rotation behavior of the AF moments during FM magnetization reversal. The results are discussed within the context of the "proximity magnetism" model. The FM magnetization behavior and the interlayer coupling are strongly dependent on the interfacial exchange coupling and the AF thickness, compared with the AF domain wall energy sigma W and the wall length delta W, respectively. A study of the exchange anisotropy in FM/AF bilayers is also presented. ©2000 The American Physical Society URL: http://link.aps.org/abstract/PRB/v62/p3933 DOI: 10.1103/PhysRevB.62.3933 PACS: 75.70.Cn, 75.30.Gw, 75.50.Ee, 75.60.Ch ------------------------------------------------------------------------ Add to article collection View PDF (307 kB) [ Previous article | Next article | Issue 6 contents ] ------------------------------------------------------------------------ References (Reference links marked with dot may require a separate subscription.) 1.

Several experimental measurements revealed the existence of spin-density wave (SDW) in Fe/Cr multilayers, e.g., E. E. Fullerton, S. D. Bader, and J. L. Robertson, Phys. Rev.

Watanabe, 79, 4914 (1997) ; The stability of incommensurate SDW and helical SDW that arises from the incompensation between the hole and electron Fermi surfaces in Fe/Cr multilayers has been theoretically investigated, e.g., Z.-P.
