Abstract
The L10 CoPt films with (0 0 1) preferred orientation are achieved by fabricating on the glass substrates and post annealing at 600° C for 30 min. The preferred orientation of [ZrO2/CoPt]n/Ag films dependence of the Ag underlayer thickness, ZrO2 and CoPt interlayer thickness is investigated. A large perpendicular magnetic anisotropy and a nearly perfect L10 CoPt (0 0 1) texture are obtained in the [ZrO2 (3 nm)/CoPt (5 nm)]3/Ag (10 nm) film. The existence of ZrO2 plays an important role in reducing the intergranular interactions and in determining the size of CoPt grains. Magnetic reversal in textured CoPt films are close to a Stoner-Wolfarth rotation.
