Research Abstract

We have investigated the anisotropy of the macroscopic electronic property for the charge/orbital ordering in quasi-two-dimensional transition metal oxides, which is strongly coupled to the crystal structural distortion with a low-symmetry. For the layered manganites with the single-layered and/or bi-layered structure, we fabricated the macroscopic single-domain of the charge/orbital ordered state, and succeeded in the observation of anisotropic dielectric, optical and elastic properties and novel collective excitation.
