. Le-système-granulaire-coeur-coquille, ferromagnétique-antiferromagnétique) Co/CoO est intéressant d'un point de vue magnétique Du point de vue du transport, les résultats n'ont pas été à la hauteur de nos attentes. La conduction dans le plan dans une assemblée d'agrégats coeur-coquille n'est probablement pas optimale pour générer des magnétorésistances très élevées, Une configuration permettant une conduction tunnel à travers un agrégat unique pourrait donner des meilleurs résultats
