The influence of interfacial roughness on the coherence of structure and magnetic coupling across barriers in Fe/MgO multilayers.
Single-crystal Fe/MgO multilayers are model systems in which to study magnetic tunnel junctions. We find that the interfacial roughness leads to the loss of coherence of the crystal structure. For thick MgO layers ferromagnetic (FM) ordering is found using polarized neutron reflectivity (PNR). For t...
