Research Subjects

  • Magneto-optics and THz experiments under ultrahigh magnetic fields
  • High-field study on quantum magnets
  • Magnet technology

We have been working on magnet technology and new measurement techniques for pulsed magnetic fields and also studying ultrahigh-magnetic-field science. Currently, we are developing THz spectroscopy techniques using quantum cascade lasers and magneto-optical spectroscopy for atomic-layer materials. We apply these techniques to van der Waals magnetic semiconductors exhibiting exotic excitons and topological Kondo insulators and excitonic insulators to understand their unconventional band structures. We are also working on megagauss science using destructive pulsed magnets.

In the van der Waals magnet FePS3, giant linear dichroism is originating from the zigzag magnetic structure. Ultrahigh magnetic fields can control the giant linear dichroism by changing the symmetry of the magnetic order.
Magnetization process of the Yafet-Kittel ferrimagnet MnCr2S4. Strong spin- lattice coupling between Mn and Cr ions is the origin of its rich phase diagram including a robust magnetization plateau.
