The magnetic states of the Ni-Fe asymmetric ring dots with partially planed outer sides were analyzed, using magnetic force microscopy and magneto-optical Kerr effect (MOKE) magnetometry. The shape of the magnetic states were analyzed by the scanning electron microscopy. The asymmetric ring dots were fabricate using electron beam lithography, DC sputtering and ion milling. The in-plane magnetic fields were found to control the magnetization chirality, either clockwise or counterclockwise, of vortical magnetizations of the assymmetric ring dots.
