Abstract
Chemically ordered 5nm-thick L1 0 FePtCu films with strong perpendicular magnetic anisotropy were post-patterned by nanoimprint lithography into a dot array over a 3mm-wide circumferential band on a 3inch Si wafer. The dots with a diameter of 30nm and a center-to-center pitch of 60nm appear as single domain and reveal an enhanced switching field as compared to the continuous film. We demonstrate successful recording on a single track using shingled writing with a conventional hard disk drive write/read head.
