Resonant scattering experiments at the iron K edge of the (002) and (006) forbidden reflections in magnetite are shown and discussed. The energy dependence of the intensity of these reflections, their dependence on the azimuthal angle and the polarization analysis are given. Experiments have been performed at room temperature and at low temperatures, below the Verwey transition. An identical behavior has been observed at high and at low temperatures, showing that the same kind of local anisotropy is present in the two phases. This experiment demonstrates the absence of either charge fluctuation between octahedral atoms in the metallic phase, or charge ordering in the insulating phase.
