Nano Magnetism

  Magnetic vortex core Copyright: © Institut2b SP-STS image of an Fe surface with adsorbate atoms. The bright spot in the center is a magnetic vortex core with a diameter of only 3.8nm.

We use spin-polarized scanning tunneling microscopy/spectroscopy (SP-STM/STS) to study magnetic nanostructures, such as magnetic vortices, skyrmions, or 2D ferromagnets. The magnetic structures are fabricated either in ultra-high vacuum by molecular beam epitaxy or by external collaborators.

Central goals are the study of magnetization dynamics using high-frequency scanning tunneling microscopy, as well as the pinning of magnetic nanostructures to surface adsorbates.
