| Abstract: | The results of a precise re-examination of neutron diffuse scattering above the Verwey transition of Fe3O4 are reported. A model to describe the properties of valence fluctuations at the B-site Fe-ions are proposed, which assumes the existance of “molecular polarons”. The experimental results of anisotropic distribution of diffuse scattering seem to give an evidence for the feasibility of the proposed model. |
