Abstract
On-specular (z direction) and offspecular (over the in-plane x-axis) neutron scattering measured with the AND/R reflectometer using a positionsensitive detector.In this experiment, columnar spin-valves having layers in the z-direction and an ellipsoidal cross-section (image, left) were made in a regular rectangular array on a silicon substrate.The in-plane Bragg peaks (sharp features) come from the repeat distance of the array, while the broader feature comes from a more local realspace structure, i.e., the micromagnetic structure of the individual spin valves averaged over many spin-valves.
