| Outline of Final Research Achievements |
We developed a technology in order to measure a dynamic behavior of the magnetic structure induced by the intense terahertz pulse irradiation. We developed a magneto-optic imaging microscope system and current-induced rectifying signal measurement system in order to probe the static and dynamic behavior of the vortex core in a thin-film permalloy disk sample. We applied an intense terahertz pulse field to the sample, and investigate the structural change. Moreover, we developed a terahertz polarization measurement system for the future magnetic control by using the polarized terahertz electromagnetic field.
