Abstract

The stability of the properties of magnetite particles in novel medicinal magnetic ointments of multipurpose application was examined by Mossbauer spectroscopy. Comparative analysis of the results obtained by model fitting of $\^$57/Fe nuclei spectra with those known for the system Fe$_3$O$_4$-${\gamma}$-Fe$_2$O$_3$ allowed to identify the phase composition of the particles. This composition, as well as that of the initial pure component in the form of a highly dispersed fraction (∼ 100${\AA}$), differs noticeably from the stoichiometric one. Despite their small sizes, the particles exhibit no superparamagnetism ( in the temperature range from 95 to 300k ). Radiative sterilization of the ointments has no effect on the magnetic component composition.
