Our goal is to control and design the novel functionalities appearing in the nanostructure of transition metal oxides by the best possible combination of the sophisticated oxide growth techniques using molecular beam epitaxy and advanced analysis techniques using synchrotron radiation. The wide range of properties exhibited by the oxide nanostructures makes them one of the most interesting groups of functional materials. The novel physical properties arise from the interface region between two different oxides. Thus, in order to control the novel functionalities, it is desired to obtain the knowledge of the interfacial electronic, magnetic, and orbital structures.
For this purpose, in our laboratory, we utilize state-oftheart spectroscopic techniques, such as angle-resolved photoemission spectroscopy and dichroic X-ray absorption spectroscopy using synchrotron radiation, which enable us to probe these structures in the nm-scale region.
