Fabrication of Spintronics Materials by Artificial Nanostructure Control



Our group works on the fabrication of materials and the fundamental study of physical phenomena for spintronics. Particularly, we are interested in magnetic ordered alloys, and fabricate nanolayered structures, tunnel junctions or composite device structures with those materials to investigate novel magnetic and magnetotransport properties. Recently we are also interested in the correlation between spin and heat currents, and investigate novel thermo-electric phenomena.

Targeted Application(s)/Industry

We hope to conduct collaborative research with a willing company for a practical application of new spintronic devices with low energy consumption and thermoelectric devices for energy harvesting.
