摘要:

电荷有序(CO)引起的电子铁电性是目前LuFe_2O_4体系中的一个重要研究课题。化学取代和结构层插层已被认为是潜在的有效方法,在我们最近的研究中,我们在此报告的结构和多铁磁性能的层状系列的LuFe2O4(LuFeO3)n(n=0,1,和2)。实验研究表明,(RFeO3)层插入导致铁电性、磁性和CO特征发生显着变化。这些结果表明,进一步探索这一系列层状成员可能证明是富有成效的。

英文摘要:

Electronic ferroelectricity from charge ordering (CO) is currently a significant issue that has been extensively investigated in the charge/spin frustrated LuFe2O4 system. Chemical substitution and structural layer intercalation have been considered as potentially effective approaches in our recent study, and we herein report on the structural and multi-ferromagnetic properties in the layered series of LuFe2O4(LuFeO3)n (n=0, 1, and 2). Experimental investigations reveal that the (RFeO3)-layer intercalation results in notable changes in ferroelectricity, magnetic properties and CO features. These results demonstrate that further exploration of this series of layered members might prove fruitful.
