At the nanoscale, magnetic properties based on electron spins are closely correlated with various transport phenomena, and we are allowed to exploit magnetic properties that are not apparent in a macroscale magnet. For spintronics enabling the mutual conversion between magnetic and electrical properties and magnetics studying on various kinds of magnetic devices, magnetic materials with high functionality by nanostructure control are indispensable. Our group works on the materials fabrication and the fundamental research on physical phenomena for magnetics and spintronics based on nanostructure-control techniques and composite design. The achievements obtained to date include the fabrication of spin-to-charge conversion materials, the demonstration of spin-orbitronics devices using artificial antiferromagnets, highly efficient thermoelectric conversion using anomalous Nernst effect of metallic superlattices, and the giant modulation of magneto-elastic properties for magnetic nitride films.
