Description

We show microstructural segregation in oxide containing [Co/Pt]n superlattice films with strong perpendicular magnetic anisotropy for application in advanced high-density magnetic recording media. By adding optimized mixtures of oxides into the Co and Pt layers of the superlattice, films with columnar grains, ~8nm grain pitch (GP), σGP/~17% and controlled intergranular exchange are demonstrated. The magnetic, microstructural and crystal properties of these films were investigated as a function of Pt thickness and oxide content.
