Cuboid polymer nanoparticles have been fabricated by substrate conformal imprint lithography (SCIL [1]). The particles were functionalized by covering them with an exchange bias layer system. They were geometrically characterized by scanning electron microscopy and magnetically by Kerr magnetometry. The functionalization by an exchange bias layer system introduces a defined magnetic anisotropy along a geometric axis of the brick-shaped particles. Agglomeration characteristics of these particles were investigated indicating that magnetic functionalization can control the self-organization of macrostructures out of designed imprinted particles.
