il serait intéressant d'explorer l'influence de l'anisotropie des couches de Cr sur l'interaction magnétique observée Cela pourrait aider à une meilleure compréhension du mécanisme à l'origine dans ce couplage magnétique Dans le but de contrôler in-situ la phase magnétique du Cr en films minces, nous avons commencé à nous intéresser aux effets d'un champ électrique appliqué au Cr dans une jonction Cr/MgO/NM dont la barrière de MgO épaisse permet d'accumuler des charges à l'interface Cr/MgO. En modifiant la concentration électronique du Cr au niveau de l'interface sous l'effet du champ électrique, une transition vers une phase commensurable devrait être induite dans le film Afin de rendre le magnétisme du Cr plus sensible à l'introduction d'une faible quantité de charges additionnelles, nous avons utilisé des alliages de CrFe au dopage proche de son point triple. Pour l'instant, il n'a pas été possible d'appliquer un champ électrique suffisant pour observer un effet discernable, mais ces expériences restent d'actualité, en améliorant la tenue de la barrière en tension, Enfin, l'objectif final de nos travaux ayant été de caractériser les couches minces de Cr dans le but de leur insertion dans des dispositifs de spintronique ,
Fe ayant été déterminée par notre étude (ainsi que le couplage associé), l'étape ultime est de mesurer l'effet de l'injection d'un courant polarisé dans des nanopiliers (tels que décrits précédemment) d'hétérostructures Cr/MgO/Fe, afin d'examiner un possible effet de couple de transfert de spin ,
