Scanning-Hall-Probe-Microscopy on perpendicular strayfields of Head-To-Head-Exchange-Bias-Layers — •Arno Ehresmann¹, Stefan Pofahl², Florian Ahrend¹ und Norbert Zingsem¹ — ¹Universität Kassel, Experimentalphysik 4, D-34419 Kassel — ²IFW-Dresden, Leibniz-Institut für Festkörper- und Werkstoffforschung

Exchange-bias-multilayer-systems with CoFe and IrMn as main components were patterned by ion-bombardment in 5mu-head-to-head-domains. On those systems scanning-hall-probe-microscopy was carried out, to measure the height dependent z-component of the stray field arising from the domainwalls. Comparison with existing theory on domain- and fieldstructure showed qualitatively good agreement, but also quantitative hints that an adjustment of that theory might be necessary.
