摘要：

On the basis of the neutron structural analysis, lattice effect on the charge/orbital-ordering transition of doped manganites has been reconsidered. We have investigated the stability of the respective e(g) orbitals dy a Madelung potential calculation, and have found a close correlation between the orbital stability and the charge-ordering transition. This observation indicates that the chemical pressure has an aspect of orbital control, besides the control of the transfer integral t between the neighboring Mn sites.
