摘要：

We report on the role of Ag underlayers in promoting (001) texture and perpendicular anisotropy in post-annealed CoPt:Ag bilayers and CoPt:Ag nanocomposites grown on Si(001). Films without Ag underlayers have a (111) texture. Thin (t(Ag) = 1.2 nm) underlayers are found to promote a strong (001) texture for CoPt thickness (t(CoPt)) up to 50 nm which gradually evolves to (111) above 100 nm. The results are compared to similar studies in CoPt:Ag nanocomposites. The angular dependece of the coercivity follows a Stoner-Wolfarth rather than a pinnig type of reversal. (C) 2003 Elsevier B.V.
