Synthesis, characterization and magnetic evaluation of praseodymium modified cerium oxide

[摘要] This paper report the synthesis, characterization and magnetic evaluation of Ce0.6Pr0.4O2system using a chemical route that involves the combustion of citrate species. The precursors were characterized by Fourier transform infrared spectroscopy (FTIR), to identify, the main vibrational bands associated with the organic material after combustion process. The structural analysis by X-ray diffraction (XRD) revealed the obtaining of an Fm-3m (225) cubic phase with a particle size around 10nm. Finally, the measurement of the magnetization as a function of applied magnetic field and of susceptibility showed a perfect paramagnetic behaviour.
