| Outline of Final Research Achievements |
In this work, we aim at introducing a pinning center into a small MoGe film. Regarding the Pacman-shaped plate, we conducted systematic studies on the vortex configuration both by experimental and theoretical methods. We discovered a novel arc-shaped configuration, and compared it with the shell model of the perfect disk. Regarding the method how to introduce the pinning center, we succeeded in fabricating a pin by ion milling method by Ar ions. The SQUID microscope observations of the vortex configurations on the Pacman plate, we compared our results with the Ginzburg-Landau calculations. We found good agreement between the two results. We also developed a SQUID sensor for the SQUID microscope, and succeeded in observing the vortex images on the MoGe films.
