"Exploring condensed-matter physics with a single spin microscope"

Vous êtes cordialement invités à la conférence "Exploring condensed-matter physics with a single spin microscope", de Vincent JACQUES, Laboratoire Charles Coulomb, Université de Montpellier and CNRS


Resumé :
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, it was shown that 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 ultrathin ferromagnets and antiferromagnetic order in
multiferroic materials.
