Exploring antiferromagnetic order at the nanoscale with a single spin microscope - Vincent Jacques - Mercredi 5 mai 2021 à 11 h

En visioconférence

Vincent Jacques, chargé de recherche laboratoire Charles Coulomb, Montpellier

Abstract

Experimental methods allowing for the detection of single spins in the solid-state, which were initially developed for quantum information science, open new avenues for the development of highly sensitive quantum sensors. In that context, the electronic spin of a single nitrogen-vacancy (NV) defect in diamond can be used as an atomic-sized magnetometer, providing an unprecedented combination of spatial resolution and magnetic sensitivity under ambient conditions. In this talk, I will illustrate how scanning-NV magnetometry can be used as a powerful tool for exploring condensed-matter physics, focusing on chiral spin textures in antiferromagnetic materials.
