Abstract

The rearrangement of the defect structure of ferrosoferric oxide Fe3O4 (magnetite) was studied by Mössbauer spectroscopy after treatment in a vortex magnetic field. The experimental dependence of the degree of structure imperfection of magnetite s on the duration of treatment in a magnetic field t MF was obtained. The s(t MF)function nonmonotonically oscillated over the range 0–100 s and experienced a relaxation transition to a new constant value, which was larger at t MF ∼ 300 s. The conclusion was drawn that very fast complex processes occurred in the crystal structure in a magnetic field, which caused irreversible changes in the defect structure of magnetite.
