N2 - Artificial glasses containing nanoscale inclusions of iron oxides, including magnetite andhematite, were obtained via the method of the high-temperature melting of rocks. The main factorsinfluencing the magnetic properties of glasses are the composition of the initial charge and the conditionsof cooling of the melt. The data of magnetic granulometry and frequency-field dependencies ofmagnetic susceptibility showed the presence of a sufficiently large superparamagnetic fraction inthe samples. Coordinated theoretical modeling using two independent models that take into considerationpossible the chemical inhomogeneity of particles and magnetostatic interaction betweenthem made it possible to calculate hysteresis characteristics corresponding to the experiment and toestimate ferrimagnetic concentrations in the samples, including the superparamagnetic fraction.
