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. The particles were geometrically characterized by scanning electron microscopy. Magnetically they were characterized 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.
