Our micromagnetic simulations and Brillouin-light-scattering results confirm that three-magnon splitting can be triggered even below threshold by exciting one of the secondary modes by magnons propagating in a waveguide next to the disk. The experiments show that stimulation is possible over an extended range of excitation powers and a wide range of frequencies around the eigenfrequencies of the secondary modes. Rate-equation calculations predict an instantaneous response to stimulation and the possibility to prematurely trigger three-magnon splitting even above threshold in a sustainable manner. These predictions are confirmed experimentally using time-resolved Brillouin-light-scattering measurements and are in a good qualitative agreement with the theoretical results. We believe that the controllable mechanism of stimulated three-magnon splitting could provide a possibility to utilize magnon-based nonlinear networks as hardware for reservoir or neuromorphic computing.</p>\n\n<p>Here, we briefly describe how the archived data for the publication "Nonlocal stimulation of three-magnon splitting in a magnetic vortex", submitted to PRL, is structured.</p>\n\n<p>"rate-equations"<br>\n- theoretical data of the temporal evolution of the spin wave modes in Fig. 4</p>\n\n<p>"micromagnetic-simulation"<br>\n- MuMax3 simulation recipes (.go files) and sample-layout masks for the<br>\nsimulations performed for Fig. 2(a,b,c).<br>\n- corresponding power spectra obtained with our "mumax3-pwsp" program<br>\n- mode profiles for stimulated and spontaneous splitting (Fig. 1(c) and Fig. 2(d))<br>\n- dispersion of the spin waves, calculated by micromagetnic simulation, shown in Fig. 1(b)</p>\n\n<p>"experiments"<br>\n- electron beam microscopy image of the sample<br>\n- intensity spectrum of the waveguide, used to calculate the approximate<br>\nfrequency/wave-vector region where the waveguide is effective (inset in Fig. 1(c))<br>\n- non-time-resolved BLS measurements, including spectra, power sweeps, etc. for<br>\nFigs 2,3 in "i3MS" folders, in more detail described by "i3MS_V1_KS_logbook.pdf"<br>\n- time-resolved BLS measurements, further explained in the corresponding subfolders<br>\n </p>", "inLanguage": { "@type": "Language", "alternateName": "eng", "name": "English" }, "@id": "https://doi.org/10.14278/rodare.365", "keywords": [ "spin wave", "nonlinear", "three-magnon splitting", "stimulation", "micromagnetic simulation", "BLS" ], "identifier": "https://doi.org/10.14278/rodare.365", "name": "Nonlocal stimulation of three-magnon splitting in a magnetic vortex", "sameAs": [ "https://www.hzdr.de/publications/Publ-31137" ], "@context": "https://schema.org/" }
