摘要：

The electronic structure of La7/8Sr1/8MnO3 was studied by using the rotation-invariant LSDA (local spin density approximation)+U formalism. We found the specific kind of charge and orbital order for ferromagnetic insulating solution in a 2aX2bX4c supercell, where a, b, and c denote cubic perovskite axes. The holes are distributed over three-line stripes in every second ac plane along the a axis. The stabilization mechanism of the hole stripe is attributed to strong p-d hybridization.
