De plus, la sensibilité du ferromagnétisme de (Ce,Co)O 2?? aux conditions en oxygène de recuits successifs semble exclure l'hypothèse d'un ferromagnétisme liéliéà la présence de nano-particules. Enfin, l'anisotropie magnétique et la valence du cobalt mesurée sont des preuves supplémentaires que le ferromagnétisme de (Ce,Co)O 2?? est intrinsèque. La comparaison des propriétés magnétiques d'un système effectivement constitué de nano-particules de cobalt dans CeO 2 ` a celle de, )O 2?? constitue la preuve la plus flagrante que le ferromagnétisme de (Ce,Co)O 2?? n'est pas dûdûà des particules de cobalt ,
