Imaging of the magnetic vortex core:
As fundamental spin structure of micro- to nanosized magnetic platelets the magnetic vortex with an in-plane curling magnetization and a perpendicular magnetized core has gained a lot of attraction in the last years From the theoretical micro magnetic point of view as well as a basic structure for spintronics applications.
Taking the advantage of the element-specificity the magnetization of layer stacks with different elemental composition can be visualized independently. This allows to measure the change in perpendicular magnetization of a Gd/Fe layer on top of a PY vortex structure separated by a Al layer by flipping the vortex core in a rotating B-field (see AG Stoll).
