Long range ordering between magnetic nanoparticles in two and three-dimensions is obtained by assisted self-assembly using pre-patterned substrates with feature size of the same order of magnitude as the diameter of the nanoparticles.
In this contribution, we will report on the first steps of this program, that are the structural characterization of patterned silicon substrates by Grazing Incidence Small Angle X-ray Scattering (GISAXS) on the laboratory high brilliance GALAXI instrument with data analysis using the BornAgain software and the structural and magnetic characterizations of monolayers of CoFe2O4 nanoparticles.
