摘要：

We report the self-organized growth of cobalt nanodot arrays using a Gd-Au Moireacute superlattice as a template. After analyzing the influence of the Co flux and the substrate temperature, we obtain the suitable parameters to maximize nanodot density, homogeneity, and individual size. Depending on the growth conditions an areal density of up to 54 Teradots/inch(2) can be achieved. Below the limit of lateral coalescence, independent nanodots made of similar to 1000 Co atoms exhibit room temperature remanent magnetization.
