Abstract
We investigated the magnetic and microstructure properties of the Fe2O3 - L i2O - B2O3 and Fe2O3 - BaO - B2O3 - Sb2O3 glass strips (with dimensions 50 mm long, 6 mm wide and about 30 divided by 100 mu m thick) subjected to var ious heat treatments. The irreversible structure changes produced by heat t reatments, were investigated by X-ray diffraction and magnetic measurements . The magnetic behaviour is discussed in terms of the evolution of the size of LiFe5O8 and BaFe12O19 crystals dispersed in the glassy matrix, With the rmal annealing.
