N2 - Magnetite single crystals with Al, Ga and Ti substitutions were measured by means of 57Fe NMR (NMR) technique. Satellite structure of NMR spectra well above the Verwey temp. was detected and analyzed to obtain information on the distribution of substituting cations on iron sublattices. It was confirmed that Al and Ti enter iron octahedral B-sites. Ga strongly prefers tetrahedral A-sites, nevertheless a low presence of Ga cations in B-sites was detected. [on SciFinder (R)]
