Imaging the excitation-power dependence of nonlinear magnon processes in momentum space

Caption

Figure 2: Imaging the excitation-power dependence of nonlinear magnon processes in momentum space. At an excitation frequency of fRF = 8.84 GHz a transition from from linear excitation (left) to a nonlinearly excited elliptical ring (center) and higher/fractional harmonics (right) can be directly accessed by magnon momentum microscopy. The red dashed lines represent theoretical dispersion iso-frequency curves for the most prominent harmonics.
