New Nature Communications paper on new method to image spin textures in antiferromagnets using Qnami QuantileverMX probes

There is nothing more rewarding to us at Qnami than seeing scientists creating break-through results using our Qnami QuantileverMX probes or Qnami ProteusQ Microscopes.  This week, the team led by Professor Vincent Jacques published a new article in Nature Communications demonstrating a new method to image spin textures in synthetic antiferromagnets using Qnami QuantileverTMMX probes.

In this article published in Nature Communications, the team led by Professor Vincent Jacques demonstrates a “new way to image non-collinear antiferromagnetic spin textures with nanoscale spatial resolution, relying on the detection of magnetic noise locally produced by thermal populations of magnons.” They achieved this using Qnami QuantileverTMMX probes, and adding a “relaxometry-based imaging mode to the scanning-NV magnetometry toolbox.”

The authors conclude that “beyond ordered antiferromagnetic structures like domain walls, spirals, and skyrmions, this imaging procedure could be extended to study magnetic order and disorder in other low-moment materials, such as domain structures in two-dimensional van der Waals systems with low Curie temperature in which spin fluctuations would become dominant under ambient conditions.”

Quantilever MX
Single NV diamond probe

Qnami QuantileverMX series probes are diamond probes with a single-spin NV center for imaging of magnetic fields.  We designed this series for magnetic imaging in nanoscale resolution. With a single NV at the center of the tip, Quantilever MX probes scan surfaces with extreme precision and allow non-perturbative analysis of a large variety of magnetic materials. Combine it with the Qnami ProteusQ for the best possible result.
