Transfert de spin, Interaction Spin‐Orbite et Dynamique d’aimantation

Ces études concernent la dynamique hyperfréquence induite par transfert de spin, la génération ou détection de courants de spin par interaction spin‐orbite et son utilisation en dynamique hyperfréquence, et enfin la stabilisation de nouvelles phases magnétiques de type skyrmion.
