Functional Magnetic Materials Group
To realize a sustainable carbon-free society, we are developing soft magnetic materials that improve the energy efficiency of power electronics and mobility, together with solid-state caloric materials characterized by the magnetic entropy. Especially, the Fe-based magnetic refrigerants and the VO2 / NiTi-based heat storage materials are aimed at social implementation by realizing new applications such as magnetic heat pump and active heat storage.
Group Research Theme
Solid-state caloric materials
By realizing a caloric effects that utilizes various form of heat with metals (LaFe, NiTi) and oxides (VO2), we are working to realize magnetic refrigeration and an active (external field-driven) heat storage.

Process for developing soft magnets
To improve soft magnetic materials related to the output of EV motors and power semiconductors, we are taking on the challenge of building metallurgy / chemical processes.
