摘要：

Magneto-optic Faraday effect in potassium-alumina-borate glasses with Fe2O3 and CoO additions made during synthesis was studied in dependence on the light wavelength, external magnetic field and temperature. It was shown that unusual magnetic properties of these glasses were due to the formation of ferrimagnetic particles which behaved at definite conditions as an ensemble of noninteracting superparamagnetic particles. Dimensions, structure, composition and blocking temperature of the particles have been determined.
