Abstract
Lattice distortions associated with charge stripe order in (formula presented) hole-doped (formula presented) are studied using synchrotron x-ray diffraction for (formula presented) and (formula presented) The propagation wave-vector and charge order correlation lengths are determined with a high accuracy, revealing that the oblique charge stripes in orthorhombic (formula presented) crystal are more disordered than the aligned stripes in tetragonal (formula presented) crystal. The twofold periodicity of lattice modulations along the c axis is explained by long-range Coulomb interactions between holes on neighboring (formula presented) planes.
