摘要：
CoO/NiFe(Ni81Fe19) layers were sputtered onto porous alumina templates to form an interconnected network structure. The antiferromagnetic/ferromagnetic coupled nanostructured bilayers exhibit large enhancements of exchange bias HE and coercivity H-c. compared to the continuous AF/FM films with same laver thickness. The temperature dependence of H-E and H-C on the NiFe thickness is reported.
