experimental study on stimulated three-magnon splitting in a magnetic disk in the vortex equilibrium state. 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> <p>Here, we briefly describe how the archived data for the publication&nbsp;&quot;Nonlocal stimulation of three-magnon splitting in a magnetic vortex&quot;, submitted&nbsp;to PRL, is structured.</p> <p>&quot;rate-equations&quot;<br> - theoretical data of the temporal evolution of the spin wave modes in Fig. 4</p> <p>&quot;micromagnetic-simulation&quot;<br> - MuMax3 simulation recipes (.go files) and sample-layout masks for the<br> simulations performed for Fig. 2(a,b,c).<br> - corresponding power spectra obtained with our &quot;mumax3-pwsp&quot; program<br> - mode profiles for stimulated and spontaneous splitting (Fig. 1(c) and Fig. 2(d))<br> - dispersion of the spin waves, calculated by micromagetnic simulation, shown in Fig. 1(b)</p> <p>&quot;experiments&quot;<br> - electron beam microscopy image of the sample<br> - intensity spectrum of the waveguide, used to calculate the approximate<br> frequency/wave-vector region where the waveguide is effective (inset in Fig. 1(c))<br> - non-time-resolved BLS measurements, including spectra, power sweeps, etc. for<br> Figs 2,3 in &quot;i3MS&quot; folders, in more detail described by &quot;i3MS_V1_KS_logbook.pdf&quot;<br> - time-resolved BLS measurements, further explained in the corresponding subfolders<br> &nbsp;</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dcat:distribution> <dcat:Distribution> <dct:rights> <dct:RightsStatement rdf:about="https://creativecommons.org/licenses/by/4.0/legalcode"> <rdfs:label>Creative Commons Attribution 4.0 International</rdfs:label> </dct:RightsStatement> </dct:rights> <dcat:accessURL rdf:resource="https://doi.org/10.14278/rodare.365"/> </dcat:Distribution> </dcat:distribution> </rdf:Description> </rdf:RDF>
