Electronic structure and hyperfine fields in non-stoichiometric magnetite above the Verwey transition
Original language description
The NMR spectra of 57Fe nuclei were measured below and above the Verwey transition temperature in single crystal samples of Fe3(1-d)O4( 0{d{0.009). The measured crystals were grown from the melt using the cold crucible technique. In a cubic phase above Verwey transition the satellite structure induced by vacancies in the octahedral sublattice is clearly resolved. The satellite lines originate from those iron nuclei in the tetrahedral sublattice that are nearest to the vacancy. Temperature dependence ofsatellite lines indicates that the presence of vacancy leads to a redistribution of the electrons in octahedral sublattice and the appearance of iron ions possessing appreciable orbital momentum.
