Mössbauer spectra of hydrous spinel iron oxide colloids and their evolution with thermal treatment have been interpreted using a modified Weiss local field model. It is found that inter-particle interactions overcome the single particle anisotropy energy. Existence of a crystalline texture within aggregates is suggested.Les spectres Mössbauer de colloides d'oxyde de fer hydraté de type spinelle et leur évolution en fonction du traitement thermique ont été interprétés à partir d'un modèle dérivé du modèle de champ moyen de Weiss. On déduit que les interactions entre les particules l'emportent sur l'énergie d'anisotropie des particules isolées. L'existence d'une texture cristalline au sein d'agrégats est suggérée
