Abstract
A novel method for the fabrication of nano-sized arrays on the surface of nanoporous anodic aluminum oxides (AAO) via evaporation is presented. The rims of the pores, which act as obstacles to the stacked atoms, cause the self-assembly of isolated arrays, and quasi-inverted-cone shape further. The magnetization reversal mechanisms of Fe arrays are investigated by inserting Pt seed arrays to form Fe/Pt bilayer arrays in order to extend the area and shorten the interval of the formation regions of Fe arrays. The magnetostatic and exchange interaction of Fe arrays are size-dependent, and the enhanced interactions cause the departure of the predominant spin rotation of single domain to be cooperative rotation in nano-storage applications.
