• nanostructuring techniques. Defects may consist of an array of voids [15] or, even simpler, of nonmagnetic nanoobjects, such as particles, optimized with respect to both mutual distance and rather low filling factor. In that case, the information-storing layer is subsequently deposited onto the nanoobjects. In

• nanostructuring and magnetism will be discussed in the following subsections. First, we present achievements and limitations of the approach. Monolayers of PS spheres have been prepared by drop-drying [21], spin-coating [22], Langmuir–Blodgett deposition or dip-coating techniques [23]. For PS sizes of 200 nm and

• , respectively. Alternatively to film deposition on size-reduced PS particles for percolated magnetic films, one may use self-assembly of inorganic spheres, such as Au nanoparticles, for nanostructuring. Commercially available Au colloid solutions with particle sizes of 60 and 40 nm have been used to prepare

• resolution up to E/ΔE = 104 and spatial resolution approaching 10 nm. While the state-of-the-art spatial resolution of X-ray microscopy is limited by nanostructuring process constrains of the objective zone plate, we show here that it is possible to overcome this through close coupling with high-level

• nanostructuring. The synthesis of 3D arrays of ligand stabilized Au nanoparticles using the self-assembly method has been reported [7], and electron beam lithography has also been used to define positioned nanoparticles at low throughput [8]. Another simple method for the formation of nanoparticle arrays is based
