Trajectory and frequency of vortex gyration in a multi-nanocontact geometry*

Li Hua-Nan^a),^b), Liu Yan^a)†, Jia Min^a), Du An^a)

The calculated instantaneous frequency of VC as a function of simulation time: (a) and (b) when only considering the Oersted field force, and (c) and (d) also taking FST into account, where the J and d are the same as those in Fig. 2(a) .
