Magnetic Nanostructures in the Lateral and Perpendicular Direction — •Hartmut Zabel — Institute for Condensed Matter Physics, Ruhr-Universität Bochum, D-44780 Bochum, Germany

Artificial magnetic nanostructures in the lateral and in the perpendicular direction are being intensively studied because of their intriguing magnetic properties and their use in spintronic devices. Perpendicularly stacked magnetic heterostructures allow the investigation of collinear and non-collinear interlayer exchange coupling, the exchange bias phenomena between ferro- and antiferromagnetic layers, as well as confinement and scaling effects of spin density wave magnetism. In the lateral direction a multitude of different shapes for ferromagnetic nanostructures can be realized such as stripes, dots, rings, squares, etc. The main interest in these nanostructures is the understanding of the domain structure in the ground state, the magnetization reversal in space and time, and the dipole interactions between the elements. In this talk an overview will be presented on investigations of magnetic superlattices and lateral magnetic nanostructures using mainly three experimental tools: vector and Bragg-MOKE, polarized neutron reflectivity, and resonant soft x-ray magnetic scattering.
