The present article reviews recent experimental investigations of spin dynamics in iron-based superconductors and their parent compounds by means of inelastic neutron scattering. It mainly focuses on the most contemporary developments in this field, pertaining to the observations of magnetic resonant modes in new superconductors, spin anisotropy of low-energy magnetic fluctuations that has now been observed in a wide range of chemical compositions and doping levels, as well as their momentum-space anisotropy incurred by the spin-nematic order. The implications of these new findings for our understanding of the superconducting state, along with the remaining unsettled challenges for neutron spectroscopy, are discussed.

Cet article fait une revue des expériences de diffusion inélastique des neutrons sur la dynamique de spin dans les supraconducteurs à base de fer et leurs composés parents. Il se concentre sur les développements les plus récents dans le domaine : l'observation des modes de résonance magnétique dans les nouveaux supraconducteurs, l'anisotropie de spin des fluctuations magnétiques de basse énergie qui est maintenant observée dans un large spectre de compositions chimiques et de dopage, ainsi que l'anisotropie dans l'espace réciproque engendrée par l'ordre nématique des spins. Les implications de ces nouvelles découvertes pour notre compréhension de la supraconductivité, ainsi que les défis dans ce domaine pour la spectroscopie de neutrons, sont discutés.
