Abstract	Cluster assemblies of 10–30 nm ferromagnetic nanoparticles in two dimensions may show magnetic vortex configurations. The average diameters of vortices with in-plane magnetization are about 2 orders of magnitude greater than the diameters of the anisotropic L1$_{0}$-FePt nanoparticles. In the present work, such configurations which also have core regions have been fabricated by a spin coating method. In the core region, the local magnetization is perpendicular to the vortex surface. This region moves by changing an applied magnetic field. The changes of magnetization in terms of the magnetic field are due to both L1$_{0}$-FePt nanoparticles and vortex microstructures formed by a collective behavior of these interactive ferromagnetic single domains.
