| Outline of Final Research Achievements |
Pump-probe optical system with a high sensitivity and large applied field has been constructed, and films of various magnetic materials with high anisotropy and low magnetic moments have been fabricated and investigated. Pseudo-two dimensional layered magnet films were successfully grown, in which coherent magnetization precessional dynamics with frequency of 0.1 THz were observed. Furthermore, the compensated ferrimagnet with ultra-high magnetic anisotropy has been grown and precessional dynamics in THz wave range have been observed. These experimental results were qualitatively explained by the phenomenological model constructed in this research.
