Micron-sized magnetic platelets in the flux-closed vortex state are characterized by an in-plane curling magnetization and a nanometer-sized perpendicularly magnetized vortex core. Having the simplest ...

The continuous downscaling in microfabrication technology has enabled the creation of magnetic microstructures and nanostructures with defined sizes and shapes. These structures are currently not only ...

Figure 1: Dynamical reversal of the vortex core: The upper section shows the "magnetic needles" of the vortex core, pointing down on the left and up on the right. The lower section shows these two ...

Figure 2: Micromagnetic simulation of the reversal of the vortex core with a short magnetic pulse. (a) Initial status: vortex core points downwards; (b) additional upwards magnetization becomes ...
