Our Researches
We are an experimental research group focusing on the development of functional novel materials with exotic properties based on spin and electron interactions. We explore broad range of material systems to understand the behaviors of spins and electrons in various metals, semiconductors, and oxides.
The topics of our interest include:
Exchange couplings between magnetic materials of different magnetic phases: ferromagnet (FM), ferrimagnet, and antiferromagnet (AFM),
Formation and manipulation of topological spin structures, Electron and spin dynamics, Magnetism in the nanostructure and at the interface,
Coupling of Magnetic, Electrical, and Mechanical properties, Hard and soft magnetic properties of low dimensional nanostructures of particles,
nanowires, and nanoplates, And any mysterious and/or unexplainable measurement results.
