Ce travail de thèse porte sur la détermination de la structure atomique, électronique et magnétique de couches ultraminces ferromagnétique et antiferromagnétique pour une meilleure compréhension du mécanisme de couplage d'échange qui peut avoir lieu à leur interface. Le couplage d'échange, effet de l'interaction entre les deux matériaux, se manifeste par un décalage du cycle d'hystérésis et une augmentation de la coercivité en-dessous de la température de blocage. Nous avons porté notre attention sur les systèmes de CoO/FePt sur Pt(001), CoO/Fe et CoO/Fe3O4 sur Ag(001) et combiné des techniques expérimentales principalement utilisant le rayonnement synchrotron pour les caractériser. Dans un premier temps, nous avons optimisé l'élaboration d...
