From: Inertia-driven resonant excitation of a magnetic skyrmion
Frequency spectra of skyrmion mode excitations under an oscillating SHST. (a,b) Frequency spectra of (a) the maximum displacement R max and (b) the area variation ΔS. Note that R max and ΔS are normalized by the amplitude H SH, and they are amplified 20 times for \({f}_{{\rm{ac}}}\ge 1\) GHz. Regimes I,II, and III correspond to the gyrotropic mode (red-shaded), the breathing mode (blue-shaded), and the inertia-driven resonant excitation (yellow-shaded), respectively.
