Exploring antiferromagnetic order at the nanoscale with a single spin microscope — •Vincent Jacques and Aurore Finco — Laboratoire Charles Coulomb, CNRS and Uni. Montpellier, France

Antiferromagnetic materials are promising platforms for next-generation spintronics owing to their fast dynamics and high robustness against parasitic magnetic fields. However, nanoscale imaging of the magnetic order in such materials with vanishing net magnetization remains a notoriously difficult task. To address this issue, quantum sensors based on nitrogen-vacancy (NV) defect in diamond have become a widespread technical solution. In this talk, I will show how scanning-NV magnetometry can be used to image chiral spin textures in antiferromagnets.
