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 […]
