Ferromagnetic induced in Cr-doped CeO2 particles
The pure phase of Cr-doped CeO2 particles have been successfully prepared by solid state reaction. The ferromagnetism (FM) at room temperature (RT) was observed in Cr-doped CeO2 particles. Oxygen vacancy defect played an important role in the magnetism of Cr-doped CeO2 particles. The lattice distortion observed on shift of the diffraction peaks that causes from oxygen vacancy. The RT-FM is enhanced after annealing in argon (Ar) atmosphere.
