The main active components of spintronic elements are ferromagnets (FMs), in which a net spin polarization is responsible for logical zeros and ones. Antiferromagnets (AFMs), in which magnetic order is accompanied by a zero net magnetic moment, play an important role in the spin-valve effect by establishing direction of FM reference layer via an exchange bias effect. However, recent demonstration of magneto-transport effects in AFMs and their ultrafast magnetization dynamics make them potential candidates that could replace FMs in spintronic devices. In this project I propose two routes that will lead to development of antiferromagnetic spintronics. The first one is focused on tuning magnetic properties of AFMs via proximity effect in AFM/AFM bilayers. The second path concentrates on the epitaxial bimetallic AFMs. In both paths the feasibility of AFM spintronics with studied AFM materials will be presented. (Polish)

Les principaux composants actifs des éléments spintroniques sont les ferromagnets (FMS), dans lesquels une polarisation du spin net est responsable des zéros et des zéros logiques. Les antiferromagnétiques (AFM), dans lesquels l’ordre magnétique est accompagné d’un moment magnétique net zéro, jouent un rôle important dans l’effet spin-valve en établissant la direction de la couche de référence FM via un effet de biais d’échange. Cependant, les récentes démonstrations des effets du transport magnéto-transport dans les AFM et leur dynamique de magnétisation ultrarapide font d’eux des candidats potentiels qui pourraient remplacer les FMS dans les dispositifs spintroniques. Dans ce projet, je propose deux voies qui mèneront au développement de la spintronique antiferromagnétique. Le premier est axé sur l’accordage des propriétés magnétiques des AFM par l’effet de proximité dans les bicouches AFM/AFM. Le deuxième chemin se concentre sur les AFM Bimétalliques épitaxiaux. Dans les deux voies, la faisabilité de l’AFM spintronics avec des matériaux AFM étudiés sera présentée. (French)
