A-site ordered manganites LnBaMn1.96Fe0.04O5 and LnBaMn1.96Fe0.04O6 areinvestigated by x-ray full-profile diffraction and Moessbauer spectroscopy.Powder samples were oriented with preferred orientation of platy crystallitesin the plane of sample surface. March-Dollase function of preferred orientationwas employed in analysing both the Rietveld patterns and the Mossbauer spectra.Combined effects of preffered orientation and vibrational anisotropy on theline area asymmetry of Mossbauer doublet are analysed. Constructive anddestructive interference between the effects of texture and vibrationalanisotropy is observed in LnBaMn1.96Fe0.04O6 and LnBaMn1.96Fe0.04O5,respectively. Both series of the manganites show the main axis of electricfield gradient perpendicular to layers (Vzz along c) with Vzz>0 in oxygen-poorseries and Vzz<0 in oxygen-rich series. Charge-orbital order (COO) meltingaround Fe dopants explains the single-site spectra observed for several Ln inboth "O5" and "O6" series, except LaBaMn1.96Fe0.04O5. However, the short-rangeCOO persists to be observed in magnetization and in Rietveld patterns.
