| Research Abstract |
Large magneto-resistance and strain-induced symmetry breaking were fond in the epitaxial thin films and their interfaces of perovskite manganites. By composing a phase diagram by using magneto-transports and nonlinear optics, the critical thickness of the d(x^2-y^2)-type orbital-order was confirmed to be about 4 nm. Under a second-harmonic microscope, the evolution of orbital-ordered domains was studied in detail, and these domains could be manipulated by photoirradiation.
