Spin waves on the nanoscale: non-linear processes and mechanical excitation
can cause magnetic switching processes triggering coherent spin wave emission in the gigahertz range [1]. Moreover, at high modulation amplitudes, we demonstrate a new class of nonlinear spin waves that oscillate [...] this geometry allows for the excitation to spin waves with almost arbitrary wave vectors.
