Abstract
This study reports the structural and magnetic properties of CeO2 nanoparticles synthesized using a simple thermal decomposition method The samples show roomtemperature ferromagnetism RTFM when thermally decomposed at above 500°C Ferromagnetic ordering occurs due to the presence of Ce3+ as confirmed by transmission electron microscopy TEM and xray absorption near edge spectroscopy XANES High resolution TEM results also reveal the Ce2O3 Ce3+ phase can be attributed to the formation of defects/oxygen vacancies at its surface The Fcenter exchange interaction has been proposed as playing an important role in the magnetic behavior of the prepared CeO2 nanoparticles
