纳米CeO2的铁磁性起源研究进展

Research Progress of Origin of Ferromagnetic in Nanoparticle CeO₂

CeO2因其具有铁磁性,在电子自旋器件方面有着广泛的应用前景。本文简要概述了近年来国内外学者关于CeO2铁磁性起源的研究成果,主要包括氧空位、磁性离子掺杂、表面Ce3+/Ce4+对、铈空位、表面Ce3+浓度、晶粒尺寸等原因。同时,对目前CeO2铁磁性起源研究存在的问题和未来研究方向进行总结和展望。

CeO2 has a broad application prospect in electronic spin devices due to its ferromagnetic. The research achievements of scholars domestic and overseas in recent years about the origins of the ferromagnetic of CeO2 was discussed in this paper briefly, mainly including oxygen vacancies, doping magnetic ions, Ce3+/Ce4+ pairs on surface, cerium vacancies, consistence of Ce3+ on surface, size of grains, et al. Meanwhile, the problems of the research and re- search direction about the origin ferromagnetic of CeO2 was summed up in this article and looked into the distance.
