Abstract

Co/Pd superlattice perpendicular films are fabricated on 2nm indium tin oxide (ITO) seed layers by DC magnetron sputtering. A film with perfect remanent squareness and highly linear demagnetization shear is obtained. Micromagnetic simulation suggests that the film has weak intergranular exchange coupling. Good SNR is obtained, but D₅₀ is reduced by the closely spaced soft underlayer and large fly height.
