Shape induced anisotropy in hybrid anti-dot arrays from guided self-assembly templates

Shape induced anisotropy in hybrid anti-dot arrays from guided self-assembly templates
The demand for higher magnetic recording densities is stimulating intense research activity into magnetism on sub-micrometer length scales. The main requirement for commercially viable products is an efficient and low-cost preparation process. Methods based on templates formed by the self-assembly of colloidal particles have been considered for various applications such as photonic materials [I], microchip reactors [2] and biosensors [3]. In this work we use ordered templates for the electro-deposition of different magnetic materials. This technique offers new opportunities, which are not easily realized by standard lithographic methods, and which allows us to create magnetic nano-structures with 3D architectures on a broad range of length scale, 20 - 1000 nm. To address limitations of self-assembly (lack of long-range order and control -of array directions) we are employing hybrid techniques using well-established Si technology to guide and confine self-assembly templates.

Abstract

The demand for higher magnetic recording densities is stimulating intense research activity into magnetism on sub-micrometer length scales. The main requirement for commercially viable products is an efficient and low-cost preparation process. Methods based on templates formed by the self-assembly of colloidal particles have been considered for various applications such as photonic materials [I], microchip reactors [2] and biosensors [3]. In this work we use ordered templates for the electro-deposition of different magnetic materials. This technique offers new opportunities, which are not easily realized by standard lithographic methods, and which allows us to create magnetic nano-structures with 3D architectures on a broad range of length scale, 20 - 1000 nm. To address limitations of self-assembly (lack of long-range order and control -of array directions) we are employing hybrid techniques using well-established Si technology to guide and confine self-assembly templates.
