| Research Abstract |
In the present study, we build a high-resolution, high-speed magnetic domain observation system with the magnetic Kerr effect microscope having" the spatial resolution of 80 nm and the high-speed response of 5 ns" by using a Hg-Xe lamp as an ultraviolet light source and a high-speed trigger control CCD camera. By using the high spatial resolution dynamic magnetic domain observation system, the magnetic domain structure of various magnetic materials for high frequencies applications have been observed.
