The magnetic and some physicochemical properties of glasses based on barium-borosilicate eutectic doped with iron and lithium oxides were studied. The magnetic permeability increases with increasing content of Fe.sub.2O.sub.3. The character of magnetic permeability remains unchanged when Fe.sub.2O.sub.3 and Li.sub.2O are introduced simultaneously. The formation of structural motifs of barium hexaferrite in glass is responsible for magnetic properties. According to EPR data, some iron ions are present in tetrahedral coordination, incorporating into the structural mesh of the glass, and the others in octahedral coordination, acting as a modifier.
