Abstract
We investigate the electronic properties and microscopic reasons of stability of the coexisting charge, magnetic and orbital ordering in half-doped manganites, using a model solved within the mean-field approximation. The Jahn–Teller terms which describe the orbital polarization at Mn 3+ sites stabilize the observed charge exchange phase, and lead to strong charge anisotropy between the bridge and corner positions along ferromagnetic zigzag chains.
