Imaging antiferromagnets with a single spin magnetometer


A consortium of research groups from the Universtié de Montpellier, Université Paris-Saclay, Universität Basel, CEA Saclay, and the Synchrotron SOLEIL has demonstrated the first real-space imaging of antiferromagnetic spin spirals in the multiferroic material bismuth iron oxide. The technique involves quantum sensing with a single spin magnetometer. A nice overview of this work can be found on the Oxitronics Group (UMPhy CNRS-Thales) website and on phys.org.
