Outline of Final Research Achievements

In this study, uniform magnetic disks of circular, triangular and square shapes were fabricated by the lithography and electroplating method, and the cluster structures formed by the disks under an external magnetic field were investigated. It was found that the cluster structures were changed depending on the number of disks and the disks' shapes. In order to make clear the cluster structures formed by the disks, a numerical simulation was carried out. As a result, it was clarified that the disks of triangular and square shapes were tended to form clusters via tip-to-tip aggregations.
