Micromagnetic simulation of excitations in triangle-shape structure. a The temporal Fourier spectrum of the vortex oscillations at different positions. The spatial distribution of oscillation amplitude under the exciting field of various frequencies, 769 MHz b, 842 MHz c, 940 MHz d, and 959 MHz e. Since the oscillation amplitudes of the vortex centers are too small, we have magnified them by 2 or 10 times labeled in each figure
