摘要: 采用基于第一性原理的全势线性缀加平面波方法(FLAPW), 计算了超晶格Fe3/Cr3的电子结构, 研究了该体系在铁磁耦合与反铁磁耦合两种状态下的磁矩分布和能态密度. 结果表明铁磁耦合状态是基态.

关键词: 电子结构, 磁性, FLAPW

Abstract: The electronic structure of Fe3/Cr3 superlattices was calculated by the full-potential linearized augmented plan-wave (FLAPW) method within first-principle formalism. The distribution of magnetic moments and state density was studied for the ferromagnetic coupling state and the antiferromagnetic coupling state respectively. The results show that the ferromagnetic coupling state is the preferable phase in the ground state.

Key words: FLAPW , magnetic property, electronic structure
