A Mossbauer study of slightly doped magnetite has revealed the occurrence of spin and charge oscillations in the B sublattice of magnetite. The Mossbauer spectra, recorded between 130K and 700K of (Fe) (M 0.05 Fe 1.95 )O 4 with M=Li + , Ni 2+ , Al 3+ , V 3+ , Cr 3+ , Ti 4+ , Sn 4+ and Mo 4+ are interpreted in terms of a charge oscillation model, which describes the electron response in narrow bands.
