| Research Abstract |
The spectroscopy under extreme conditions has been studied and established at the energy from Fermi level to 10 meV above which is important energy region for understanding electronic states of strongly correlated electron systems. Optical studies in an infrared-terahertz region using a synchrotron radiation (SR) or a free electron laser (FEL) that have an advantage of brightness at around the wavelength of 100 μm have been investigated for evolving spectro-microscopy for small samples under low temperature, high pressure, and strong magnetic field. The success of polarization control of FEL enabled experiments in an infrared-terahertz region about vibrational circular dichroism (VCD) in optically active compounds or magnetically circular dichroism (MCD) in magnetic compounds. High speed spectroscopic imaging experiments were realized as a pulse-by-pulse raster scan method.
