We are doing researches on magnetism and electron spin physics of solids, mainly for the surfaces, ultra-thin films, and nano-structured materials, where the key words are “spin” and “nano”. When materials become smaller or thinner, there appear novel magnetic and spin-related properties, because of the broken symmetry. In the experiments, we are using Spin-Polarized Scanning Electron Microscope (Spin SEM), Spin-Polarized Scanning Tunneling Microscope (STM), Spin-Polarized Spectroscope, 4 Probe with SEM/STM, Physical Property Measurement System etc, which we developed or modified for our own use.
