Exploring Frontier of Magnetism in High Magnetic Fields

The main subject of our group is to investigate basic principles to control condensed matters by using strong pulsed and steady magnetic fields. A magnetic field is a unique external environment because of the precise controllability in the intensity, time structure, and hysteresis. Novel magnetic state and exotic electronic phase are induced by high magnetic fields. For example, it enables us to control the quantum state of nano-scale magnet. Such knowledge is essential for quantum information science and develoment of information material. The original and unique advanced spectrometers such as THz- ESR, high field X-day spectrometer are used for these researches.

A split-pair magnet used for for X-ray diffraction with X-ray free electron laser. In the extremely compact volume of about15 cm3, ultra strong magnetic fields over 30 T can be generated. We have succeeded in the observation of very weak signal caused by the charge density wave in high Tc superconductor.
