Strongly correlated electronic oxides have an attractive feature that their electrical, magnetic, and optical properties vary widely depending on the valence state of the constituent cations. We are particularly focusing on iron oxides which are non-toxic, environmentally friendly, and abundant resources on earth. We aim to create new functional iron oxide materials by controlling the valence states and crystal structures at the atomic level and develop high efficiency solar-energy conversiont systems and room-temperature spintronics devices based on them.

Recently, energy harvesting technologies have been widely investigated. However, most of them are well-known physical phenomena. It is desired to create innovative energy conversion technologies based on unprecedented concepts and theories in order to secure and supply stable electrical energy in the future advanced information society and environmantally friendly society. We focus on the "Yuragi (fluctuation)" of electrical and magnetic functions and aim to establish new principles by utilizing the ultra-high sensitivity of Yuragi systems to external stimuli such as light and heat.
