Imaging magnetic structures at the nanoscale with Qnami ProteusQ

Magnetic materials are interesting platforms since they allow both to study fundamental material properties, and boost technology development. A wide variety of magnetic phenomena in various material systems get expressed in complex magnetic structures at the nanoscale: antiferromagnetic spintronics, skyrmions, spinwaves, 2D magnets, or Magnetic Random Access Memories.

The common need to explore such phenomena is to resolve minute magnetic fields with a nanoscale spatial resolution. This is what you can do with Qnami ProteusQ.

Here we present the Qnami ProteusQ Imaging Modalities implemented in the system software LabQ.
The four different modalities allow you to:

  • Identify magnetic domain walls and study their dynamics,
  • Characterize magnetic textures at the surface of antiferromagnets,
  • Reveal complex ferromagnetic structures in multilayer strong ferromagnets,
  • And much more…
