Abstract

We have explored spin, charge, and orbitally ordered states in La1-xSrxMnO3 (0<x<1/2) using model Hartree-Fock calculations on d-p-type lattice models. At x=1/8, several charge and orbitally modulated states are found to be stable and almost degenerate in energy with a homogeneous ferromagnetic state. The present calculation indicates that a ferromagnetic state with a charge modulation along the c axis which is consistent with the experiment by Yamada et al. might be responsible for the anomalous behavior around x=1/8.
