dc.description.abstract | The CE magnetic order of charge-orbital ordering pattern in half-doped manganites is characterized by the formation of orbital stripe as well as the checkerboard-type charge ordering. The quasi-one-dimensionality in the orbital arrangement results in the in-plane anisotropy of physical properties, e.g., optical spectra with light polarization along the orbital stripe exhibits the larger energy-gap state than those along the orbital chain. It has been recently reported that the spontaneous rotation of orbital stripe with variation of temperature (T) occurs in a bilayer manganite, Pr(Sr0.1Ca0.9)(2)Mn2O7. To confirm this peculiar behavior, we performed optical measurements of a single domain sample with polarization dependence. While the in-plane optical anisotropy is identified together with the initial formation of the charge-orbital ordering, it is reversed at a lower T, where the orbital stripe is rotated by 90 degrees.
