Résumé
Des verres homogènes du type BaO-Fe2O3 (39-63 mol.% Fe2O3) avec B2O3 en petite quantité ont été obtenus par trempe à partir de l'état liquide. L'étude Mössbauer montre que le verre comporte essentiellement des mailles tetraédriques de Fe3+O4 et qu'il existe un ordre antiferromagnétique à courte distance à basse température.
Abstract
Homogeneous glasses of the iron-rich BaO-Fe2O3 system (39-63 mol.% Fe2O3) with a small amount of B2O3 are prepared by splat cooling method. Mössbauer study reveals that the glass mainly consists of tetrahedral network of Fe3+O4 and a short range antiferromagnetic order is formed at low temperatures.
