Abstract

Abstract: We have studied the magnetic properties of two-phase borosilicate glasses with matrices containing a mixture of β-Fe₂O₃ and Fe₃O₄ nanoparticles. The dimensions of the oxide nanoparticles are determined, and the temperature of blocking (T_B ~ 330 K) of the ensemble of superparamagnetic nanoparticles is estimated. It is also established that a sharp increase in the specific magnetization of these glasses when the Néel temperature is approached (and, below it, for bulk β-Fe₂O₃).
