Abstract
A soft-chemistry method is used to synthesize zinc ferrite nanoparticles to prepare a magnetic fluid. We investigate here their internal structure by X-ray Absorption Near Edge Spectroscopy (XANES) and X-Ray Diffraction (XRD). A cross analysis of XANES and Rietveld refinement of XRD spectra shows non-equilibrium site occupancy with respect to bulk zinc ferrite, suggesting a cation redistribution that enhances the magnetic and magneto-optical responses of the nanoparticles.
Research Highlights► Local structure of ZnFe2O4 nanoparticles synthesized by soft-chemistry. ► Qualitative analysis of experimental XANES spectra indicated cation redistribution. ► Rietveld refinement of X-ray diffraction data gives the inversion degree.
