Research Abstract

By means of both techniques of Interference Lithography using UV laser and UHV deposition, we fabricated nano-scale structures which consist of magnetic multilayer in x and y directions, and in-plane periodic arrays in z-direction. We measured the effect of the nano-patterned structure on magnetic, optical, and electrical properties, and the response against a current flow in arrays.
