Abstract

The structural changes associated with the charge ordering (CO) transition in layered La(0.5)Sr(1.5)MnO(4) have been determined by electron diffraction using the multislice least-squares method. The results demonstrate that the structural deformations of the Mn(3+)O(6) octahedra can be well characterized by a transverse modulation wave along the direction. Based on these structural data, we have performed a theoretical calculation of the electronic structure by density functional theory plus the on-site Coulomb interaction U. The resultant density of states exhibits a clear band gap at the Fermi level for this low-temperature CO insulating state. It is also noted that the essential Jahn-Teller effects in this layered system can evidently affect the electronic structures and orbital hybridization appearing with the CO transition. Charge disproportionation and orbital ordering in La(0.5)Sr(1.5)MnO(4) have been extensively discussed in comparison with the data obtained for the cubic perovskite La(0.5)Ca(0.5)MnO(3).
