MOKE: Images of Micromagnets
Whisker
The first video clip shows the process of establishing domain structures by exposing the target to a time-variant magnetic field. Here the target was a Whisker. The lumminance of the target corresponds directly to the magntic field strength. The images captured have been overlayed in software by vectors of the magnetic flux direction.
CU-Sheet
In this second clip the target was a cupper sheet. Contrary to the Whisker we observe a different domain pattern (a stacked one compared to the Landau-Lifshitz structure before). Furthermore defects in the target material lead to earlier domain forming.
The Project Report and a Poster are unfortunatly available in German only.
