    Abstract

    We have studied the structural modifications related to the charge-orbital ordering for single-layered manganites Nd1-xCa1+xMnO 4 with both commensurate and incommensurate doping levels (0.55≦ x ≦0.75). High-resolution electron microscopy (HREM) revealed transverse and sinusoidal structural modulations with a doping-level-dependent period of d s = a/(1-x) in the charge-orbital ordered phases. We discuss the possibility of an orbital-density wave as well as a charge-density wave based on the HREM observation of the single-layered manganites.
