Abstract:

RT ferromagnetism was observed in nanoparticles of Fe-doped CeO2 (i.e., Ce0.97Fe0.03O2) synthesized by a sol–gel method. The undoped and Fe-doped CeO2 were characterized by XRD, Raman spectroscopy, TEM, and VSM. The undoped samples and Ce0.97Fe0.03O2 precursor exhibit a diamagnetic behavior. The 673 K-calcined Ce0.97Fe0.03O2 sample is paramagnetic whereas 773 and 873 K-calcined Ce0.97Fe0.03O2 samples are ferromagnetism having the magnetizations of 4.65 × 10−3 emu/g and 6.20 × 10−3 emu/g at 10 kOe, respectively. Our results indicate that the ferromagnetic property is intrinsic to the Fe-doped CeO2 system and is not a result of any secondary magnetic phase or cluster formation.
