Micromagnetic simulation of excitations in parallelogram-shape structure. a The temporal Fourier spectrum of the vortex oscillations at different positions. The spatial distribution of oscillation amplitude under the exciting field with different frequencies, 767 MHz b, 844 MHz c, 940 MHz d, and 964 MHz e. The simulation time is 100 ns. Since the oscillation amplitudes of the vortices centers are too small, we have magnified them by 2 or 10 times labeled in each figure
