Control of magnetic vortex wall chirality, polarity and position by a magnetic field

The seeding of vortex domain walls in V-shaped nanowires by a magnetic field has been investigated via simulations and Scanning Electron Microscopy with Polarization Analysis (SEMPA). It is found that the orientation of the magnetic field can be used to purposely tune the chirality, polarity and position of single vortex domain walls in soft magnetic nanowires.
