Abstract
The present invention relates to a method for producing an ordered array of nanoparticles on a substrate surface and to a nanomaterial having such an ordered array of nanoparticles. Particularly, but not exclusively, the invention relates to the provision of an ordered array of magnetic nanocrystals on a substrate surface. Although the present invention is not limited to the production of a magnetic array, one important object of the present invention is the production of a material suitable for use as an ultra high density magnetic data storage medium. According to the present invention there is provided a method of producing a structure comprising a plurality of nanoparticles distributed across a surface of a substrate in a predetermined array, the method comprising the steps of: i) providing a substrate which has a passivated surface; ii) depositing nanoparticles on to said surface; and iii) displacing said particles over said surface to configure them in said predetermined array.
