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>", "related_identifiers": [ { "scheme": "url", "relation": "isIdenticalTo", "identifier": "https://www.hzdr.de/publications/Publ-31137" }, { "scheme": "url", "relation": "isPartOf", "identifier": "https://arxiv.org/abs/2005.12663" }, { "scheme": "url", "relation": "isReferencedBy", "identifier": "https://www.hzdr.de/publications/Publ-31058" }, { "scheme": "doi", "relation": "isVersionOf", "identifier": "10.14278/rodare.364" } ], "title": "Nonlocal stimulation of three-magnon splitting in a magnetic vortex", "keywords": [ "spin wave", "nonlinear", "three-magnon splitting", "stimulation", "micromagnetic simulation", "BLS" ], "pub_id": "31137", "publication_date": "2020-06-11" }, "links": { "badge": "https://rodare.hzdr.de/badge/doi/10.14278/rodare.365.svg", "doi": "https://doi.org/10.14278/rodare.365", "conceptbadge": "https://rodare.hzdr.de/badge/doi/10.14278/rodare.364.svg", "conceptdoi": "https://doi.org/10.14278/rodare.364", "bucket": "https://rodare.hzdr.de/api/files/74bda886-8dbf-448b-86f5-70fdb9cb4c6c", "html": "https://rodare.hzdr.de/record/365", "latest": "https://rodare.hzdr.de/api/records/365", "latest_html": "https://rodare.hzdr.de/record/365" }, "conceptdoi": "10.14278/rodare.364", "owners": [ 198 ], "id": 365, "files": [ { "size": 96443955, "links": { "self": "https://rodare.hzdr.de/api/files/74bda886-8dbf-448b-86f5-70fdb9cb4c6c/data.zip" }, "checksum": "md5:c0dcce25174fe0c0f064b38686d3d4c4", "type": "zip", "bucket": "74bda886-8dbf-448b-86f5-70fdb9cb4c6c", "key": "data.zip" } ], "stats": { "volume": 28643854635.0, "unique_downloads": 55.0, "version_unique_downloads": 55.0, "unique_views": 477.0, "downloads": 297.0, "version_unique_views": 477.0, "version_views": 907.0, "version_downloads": 297.0, "version_volume": 28643854635.0, "views": 907.0 }, "created": "2020-06-11T07:57:35.334683+00:00", "revision": 8, "conceptrecid": "364", "updated": "2020-10-30T12:02:17.586857+00:00", "doi": "10.14278/rodare.365" }
