| Research Abstract |
Measurement with high time resolution on excitation process of magnetic resonance phenomenon in THz frequency region is important for analysis of basic behavior of material in high magnetic field. In this research subject, a high power THz radiation generated by a stable THz radiation source- gyrotron is irradiated on the sample installed in the high magnetic field and the behavior of the sample is analyzed by an X-ray circular dichroism with high time resolution. Obtained results are as follows, 1) Using a THz radiation source-Gyrotron FU II developed in University of Fukui and an ESR device installed in the European Synchrotron Radiation Facility (ESRF) in Grunoble, France, we have carried out successfully the operation test of the measurement device with high time resolution for analysis of excitation process of magnetic resonance by use of an X-ray circular dichroism. We are intending to advance the application of the developed device to material science in the world. In addition, we will develop the device further to higher frequency region and combined quantum beam technology between an X-ray and a THz radiation beam.
