Abstract: | A magnetooptic Kerr setup is designed for investigating the dynamic properties of domain walls in thin ferromagnetic films
subjected to an external magnetic field in the temperature range 20–150°C. With this setup, the method of interrupted magnetization
is implemented and the magnetic (domain) structure is visualized based on the meridional Kerr effect. The domain structure
is displayed on a PC monitor using a Nikon DXM 1200 high-resolution digital video camera. A dedicated software makes it possible
to automatize measurements and data processing. |
