| 中文摘要 | The charge/orbital ordering (COO) of the layered mixed-valence manganites (La, Sr)(n+1)MnnO3n+1 (n = 1 and 2) is examined by first-principles calculations and discussed in comparison with the La0.5Ca0.5MnO3 perovskite phase (n = infinity). The results demonstrated that the layered structural features could yield not only visibly weak coupling between Mn- O layers but also various features in the orbital ordering associated with different types of local structural distortions. In both La0.5Sr1.5MnO4 (n = 1) and LaSr2Mn2O7 (n = 2) phases, the orbital ordering can be chiefly assigned to the d(x)(-y)(2)(2) orbital, in contrast with the zigzag-type d(z)(2) orbital ordering in the n = infinity perovskite phase. Our theoretical analysis shows that a variety of essential factors, including the local structural distortions of the MnO6 octahedra, the on-site Coulomb interaction, and magnetic interaction, have to be properly considered in order to achieve acceptable COO ground states for the layered variants in (La, Sr)(n+1)MnnO3n+1. |
