Comparative study of the microstructural and magnetic properties of spinel ferrites obtained by co-precipitation

Spinel cubic ferrites were obtained by co-precipitation methods. Specific structural parameters were obtained by X-ray diffraction (XRD) spectra fitting refinement using the Rietveld method. Comparison of the magnetic properties was performed by vibrational magnetometry and Mossbauer spectroscopy in transmission mode. The particle morphology was studied by transmission electron microscopy (TEM) with in-situ microanalysis using energy dispersive spectrometry. The different morphologies, sizes, material properties and magnetic behaviour between these spinels were analysed and discussed. (C) 2003 Elsevier B.V. All rights reserved.
