Three-magnon scattering, a nonlinear process in which a high-energy magnon splits into two low-energy magnons with energy and momentum conservation, has been widely studied in the magnonics community. Here, we report experimental observation of nonlinear three-magnon scattering in La0.67Sr0.33MnO3 thin films with low magnetic damping(~ 10-4) by all-electric and angle-resolved spin wave spectroscopy. The reflection spectra of the spin wave resonance wit... 相似文献
