Creating new functional materials via spin control of nanostructures

Nanometer-sized spin materials, which enable electron spin control, are expected to lead to new functional devices. Our laboratory is committed to innovating spin metamaterials to develop ultra-low power petabyte memories(magnetic and/or optical) and to addressing global warming and other energy-related problems.
