Descrição: We report on the role of Ag underlayers in promoting (0 0 1) texture and perpendicular anisotropy in post-annealed CoPt:Ag bilayers and CoPt:Ag nanocomposites grown on Si(0 0 1). Films without Ag underlayers have a (1 1 1) texture. Thin ( t Ag=1.2 nm) underlayers are found to promote a strong (0 0 1) texture for CoPt thickness ( t CoPt) up to 50 nm which gradually evolves to (1 1 1) 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.
