The influence of finite dimensions on the exchange bias effect in patterned polycrystalline Co/CoO ferromagnet/antiferromagnet exchange bias systems was studied. Magnetization measurements on the smallest structures reveal that the exchange bias shift increases as the structure size becomes smaller. Off-specular neutron scattering experiments were used to study the asymmetric magnetization reversal behaviour. (C) 2006 Elsevier B.V. All rights reserved.
