Abstract

CoPtCu nanocomposite films were prepared by magnetron sputtering. The dependences of texture and magnetic properties on film thickness, Cu atomic fraction and annealing conditions are investigated. After annealing at 640°C, (001) orientation was achieved in the Co₄₁Pt₄₉Cu₁₀ film, with a coercivity of 8.4 kOe and magnetization of 650 emu/cm³. A short-range domain structure is observed indicating weak inter-grains exchange coupling after annealing. The results suggest that this system might be applicable to ultra high-density perpendicular hybrid recording media.
