摘要：

We have investigated the electric-field effect on the orbital-ordered state of e(g) electrons for layered manganites Nd1-xSr1+xMnO4 near the phase boundary between antiferro d(3x)(2)-r(2)/d(3y)(2)-r(2) and ferro d(3x)(2)-r(2) orbital-ordered phases. By means of a polarization microscope in crossed-Nicol configuration, we can distinguish these two orbital-ordered phases, and observed the electric-field switching between the two phases. This indicates that the electric-field can affect the directional order of orbital, and the system with the two competitive orbital-ordered states bears the orbital analog of the liquid-crystal functionality.
