Abstract—Nanoparticles that are formed in the course of additional heat treatment in borate glasses containing
iron and manganese oxide additives at low concentrations are directly observed for the first time using electron
microscopy. The size, the shape, and the structure of nanoparticles and their volume distribution in the glass
matrix are determined. Correlations between the nanoparticle parameters and the magnetic and magneto-optical
properties of the glasses containing these particles are revealed.
