| Outline of Final Research Achievements |
The purpose of this research is ultrafast coherent control of magnetization using polarized ultrashort pulses. We investigated hexagonal manganite excited via the inverse magneto-optical effect and probed via the linear- and nonlinear magneto-optical effect. For the first time, we detected time-resolved coherent magnon via the nonlinear magneto-optical effect. Temperature dependence of the magnon relaxation time was performed and its mechanism was discussed. We also investigated transmission of spin wave through an air gap, both from the experiment and calculation. As a result, we observed evanescent spin wave.
