[Revue des interactions magnétiques dans les supraconducteurs à base de fer]
La supraconductivité à haute température dans les pnictures et les chalcogénures de fer émerge quand une phase magnétique est supprimée. Le caractère multi-orbital et la force des corrélations sont sous-jacents à cette phénoménologie complexe, faisant appel à la douceur magnétique et aux anisotropies, dans lesquelles le couplage de Hund joue un rôle important. Nous passons ici en revue les différentes approches théoriques utilisées pour décrire les interactions magnétiques dans ces systèmes. Nous montrons que la prise en compte du degré de liberté orbital nous permet d'unifier dans un seul diagramme de phases les principaux mécanismes proposés pour expliquer l'ordre dans les pnictures de fer : supraconductivité nesting-driven, échange entre spins localisés et état magnétique induit par couplage de Hund avec différenciation orbitale. La comparaison des estimations théoriques et des résultats expérimentaux nous permet de localiser les supraconducteurs à base de fer dans le diagramme de phases. De plus, la physique orbitale est cruciale pour approcher la douceur magnétique, les propriétés dépendant du dopage ainsi que les anisotropies.
High-temperature superconductivity in iron pnictides and chalcogenides emerges when a magnetic phase is suppressed. The multi-orbital character and the strength of correlations underlie this complex phenomenology, involving magnetic softness and anisotropies, with Hund's coupling playing an important role. We review here the different theoretical approaches used to describe the magnetic interactions in these systems. We show that taking into account the orbital degree of freedom allows us to unify in a single phase diagram the main mechanisms proposed to explain the order in iron pnictides: nesting-driven superconductivity, exchange between localised spins, and Hund-induced magnetic state with orbital differentiation. Comparison of theoretical estimates and experimental results helps locate the Fe superconductors in the phase diagram. In addition, orbital physics is crucial to address the magnetic softness, the doping-dependent properties, and the anisotropies.

[208] A reversal in the dependence on interactions of the and at high interactions has been reported for some chalcogenides, consistent with a reversal of the on-site interactions of these two orbitals, see [189].
[209] In LaFePO the mass is higher for orbitals because the crystal field splitting puts the orbitals below the orbitals, thereby promoting a ground state with configuration in the atomic limit, see [213].
