Specular Reflectivity and Off-specular scattering from artificial magnetic domain patterns
The proposed study is a feasibility experiment for the investigation of artificially designed in-plane magnetic domain patterns by polarised neutron reflectometry and off-specular scattering. Stripe shaped domains with in-plane magnetizations are arranged in a head-to-head and tail-to-tail configuration, leading to a charged domain wall equivalent to a magnetization component perpendicular to the surface of the thin film. The magnetic stray field landscape arising from these submicron sized magnetic structures has the potential for positioning and transporting magnetic micro- and nano-objects in liquids and therefore provide an excellent platform for various lab-on-a-chip applications. From this experiment we hope to evaluate in which detail qualitative and quantitative information can be obtained from specular and off-specular neutron scattering. The information obtained will provide the basis for future tailoring and applications of the magnetic templates.
