L'examen et l'interprétation des propriétés magnétiques de verres d'hypertrempe dans deux systèmes xFe2O3 (1-x) [BaO, B2O3] et xFe2O3 (1-x) [Li2O,B2O3] conduisent suivant la teneur en Fe2O3 à des modèles de coordination tétraédrique ou octaédrique déformés. Dans ces verres les atomes Fe3+ sont suivant les concentrations croissantes en Fe2O3 successivement -isolés, -sous forme de dimères ou trimères, -dans des clusters en interactions, -enfin dans des microcristaux.Magnetic properties of splat cooled glasses have been performed in ternary systems xFe2O3 (1-x) [BaO, B2O3] and xFe2O3 (1-x) [Li2O, B2O3]. In respect of Fe2O3 content the interpretation of experimental data leads to structural models with deformed tetrahedral and octahedral coordi...
