| Research Abstract |
I have studied dynamics of magnetic ultra thin films using laser threshold magnetic circular dichroism photoelectron emission microscope, which has femtosecond time resolution as well as ~ 50 nmspatial resolutions. Direct observation of the precession motion of magnetic thin films has not been achieved due to its subtle change. However I have enhanced the magnetic sensitivity and time stability of the microscope, which is ten times better than those before this project. This development enables us to make the first observation of magnetic domain dynamics about the molecular adsorption on to magnetic ultra thin films.
