Many practical materials are complex systems with spatial hierarchical structures
ranging from atoms to millimeters. Therefore, when designing and developing newmaterials, it is important to clarify the correlation between structure and function at
the mesoscale, which connects the micro and macro scales. By utilizing imaging andspectroscopic techniques using synchrotron radiation, it is possible to visualize thestructure, elements, and electronic state of the entire practical bulk material in a
multidimensional manner. We develop next-generation synchrotron radiation

We study structure, transformation and mechanical deformation in metallic
materials with random atomic configuration such as metallic glasses or amorphousalloys using the advanced analysis and interdisciplinary approach. Such random
atomic structured materials have significantly different properties with those of
conventional crystalline alloys and are highly expected for industrial uses in thenext generation. Especially, we focus on a relaxation phenomenon in metallic

Theme of Research
There are many inorganic compounds that have not been discovered or whosefunctions have not been completely revealed and understood. We aim to explore
novel inorganic compounds and develop new synthesis processes for high-quality
samples in order to create new inorganic materials such as thermoelectric materials,
hard ceramics and metallic materials, dielectric materials, and superconductors. To
achieve these goals, we analyze the crystal structures of the obtained compounds,
focusing on mainly non-oxide compounds, and characterize their material properties
and their functionalities, such as electronic and thermal properties.
Catalyst is one of the key materials for realizing a decarbonized society. In recent
years, precious metal–free and development of precious metal alternative alloy
catalysts have become the most important issues. The research of our laboratory is
focused on creation of catalytic materials with excellent properties in terms ofmetallurgy and exploration of alloys with novel structures. The main research theme
is to design and fabricate metallic materials with novel catalytic functions. We will
create a catalytic material with a unique structure and morphology that cannot be
obtained using conventional chemical methods. We will also study about thesynthesis and structure of quasicrystal related intermetallic compounds, to takeadvantage of the knowledge gained as the basis of novel catalyst development.
Local crystal structure analysis is becoming increasingly important in functional
materials that exhibit intriguing physical properties induced by nanoscale local
structures and crystal interfaces. Using the convergent-beam electron diffraction(CBED) method with nano-electron probe, we developed a quantitative local
structure analysis method and applied it to various functional materials such as
ferroelectric ceramics. Furthermore, we are working on the development of a new
method to study spatial variations of local structures and electrostatic potential
distributions in crystal interfaces and nanodomain structures.
In pursuit of the next generation of multifunctional thin film materials, significant
research efforts are directed towards the development of multi-layered or nanocomposite metal-ceramic films. Especially, nano-composite films preparation withmagnetic-metal nano-particles dispersed in the dielectric ceramics is researchaiming at the expression of multifunctional physical property by the nano quantum
effect (proximity effect), that is, the seepage effect of the physical property
governed by the three-dimensional interface state.
Our laboratory has recently discovered novel multifunctional properties such as the'Tunnel Magneto-Dielectric (TMD) effect' and 'Tunnel Magneto-Optical (TMO)
effect', which allow for the manipulation of dielectric constant and transmittancethrough changes in magnetic field. We are actively engaged in enhancing thefunctionality and elucidating the mechanisms behind these new effects, while also
