Imaging non-collinear antiferromagnetic textures via single spin relaxometry

The team led by Vincent Jacques demonstrates 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.”
