    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)

    Die wichtigsten aktiven Komponenten von spintronischen Elementen sind Ferromagnete (FMS), bei denen eine Netzspin Polarisation für logische Nullen und solche verantwortlich ist. Antiferromagnete (AFMs), in denen magnetische Ordnung von einem Null-Netto-Magnetmoment begleitet wird, spielen eine wichtige Rolle im Spin-Ventil-Effekt, indem sie die Richtung der FM-Referenzschicht über einen Austausch-Bias-Effekt bestimmen. Die jüngste Demonstration von Magneto-Transport-Effekten in AFMs und ihrer ultraschnellen Magnetisierungsdynamik macht sie jedoch zu potenziellen Kandidaten, die FMS in spintronic Geräten ersetzen könnten. In diesem Projekt schlage ich zwei Routen vor, die zur Entwicklung der antiferromagnetischen Spintronik führen werden. Die erste konzentriert sich auf das Tuning magnetischer Eigenschaften von AFMs durch Näherungseffekt in AFM/AFM-Bilayern. Der zweite Weg konzentriert sich auf die epitaxielle Bimetallic AFMs. Auf beiden Wegen wird die Machbarkeit von AFM spintronics mit untersuchten AFM-Materialien vorgestellt. (German)

    De belangrijkste actieve componenten van spintronic elementen zijn ferromagneten (FMS), waarbij een netto spin polarisatie verantwoordelijk is voor logische nullen en enen. Antiferromagneten (AFM’s), waarbij de magnetische volgorde gepaard gaat met een nul netto magnetisch moment, spelen een belangrijke rol in het spin-klepeffect door richting van FM-referentielaag te bepalen via een exchange bias-effect. Echter, recente demonstratie van magneto-transport effecten in AFM’s en hun Ultrasnelle magnetisatie dynamiek maken hen potentiële kandidaten die FMS kunnen vervangen in spintronic apparaten. In dit project stel ik twee routes voor die zullen leiden tot de ontwikkeling van antiferromagnetische spintronica. De eerste is gericht op het afstemmen van magnetische eigenschappen van AFM’s via proximity-effect in AFM/AFM bilayers. Het tweede pad concentreert zich op de epitaxiale bimetaal AFM’s. In beide paden wordt de haalbaarheid van AFM spintronics met bestudeerde AFM materialen gepresenteerd. (Dutch)

    I principali componenti attivi degli elementi spintronici sono i ferromagneti (FMS), in cui una polarizzazione netta di spin è responsabile di zeri logici e di quelli. Gli antiferromagneti (AFM), in cui l'ordine magnetico è accompagnato da un momento magnetico netto zero, svolgono un ruolo importante nell'effetto spin-valvola stabilendo la direzione dello strato di riferimento FM tramite un effetto di polarizzazione dello scambio. Tuttavia, la recente dimostrazione degli effetti magneto-trasporti negli AFM e la loro dinamica di magnetizzazione ultraveloce li rendono potenziali candidati che potrebbero sostituire l'FMS nei dispositivi spintronic. In questo progetto propongo due percorsi che porteranno allo sviluppo della spintronica antiferromagnetica. Il primo è focalizzato sulla messa a punto delle proprietà magnetiche degli AFM tramite effetto di prossimità nei bilayer AFM/AFM. Il secondo percorso si concentra sugli AFM bimetallici epitassiali. In entrambi i percorsi verrà presentata la fattibilità di AFM spintronics con materiali AFM studiati. (Italian)
