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></subfield> </datafield> <datafield tag="653" ind1=" " ind2=" "> <subfield code="a">spin wave</subfield> </datafield> <datafield tag="653" ind1=" " ind2=" "> <subfield code="a">nonlinear</subfield> </datafield> <datafield tag="653" ind1=" " ind2=" "> <subfield code="a">three-magnon splitting</subfield> </datafield> <datafield tag="653" ind1=" " ind2=" "> <subfield code="a">stimulation</subfield> </datafield> <datafield tag="653" ind1=" " ind2=" "> <subfield code="a">micromagnetic simulation</subfield> </datafield> <datafield tag="653" ind1=" " ind2=" "> <subfield code="a">BLS</subfield> </datafield> <controlfield tag="005">20201030120217.0</controlfield> <datafield tag="542" ind1=" " ind2=" "> <subfield code="l">open</subfield> </datafield> <datafield tag="856" ind1="4" ind2=" "> <subfield code="s">96443955</subfield> <subfield code="u">https://rodare.hzdr.de/record/365/files/data.zip</subfield> <subfield code="z">md5:c0dcce25174fe0c0f064b38686d3d4c4</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Schultheiß, Katrin</subfield> <subfield code="0">(orcid)0000-0002-3382-5442</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Hula, Tobias</subfield> <subfield code="0">(orcid)0000-0002-1811-8862</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Verba, Roman</subfield> <subfield code="u">Institute of Magnetism, Kyiv 03142, Ukraine</subfield> <subfield code="0">(orcid)0000-0001-8811-6232</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Faßbender, Jürgen</subfield> <subfield code="0">(orcid)0000-0003-3893-9630</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Kakay, Attila</subfield> <subfield code="0">(orcid)0000-0002-3195-219X</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Schultheiß, Helmut</subfield> <subfield code="0">(orcid)0000-0002-6727-5098</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="a">user-hzdr</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="a">user-rodare</subfield> </datafield> <datafield tag="024" ind1=" " ind2=" "> <subfield code="a">10.14278/rodare.365</subfield> <subfield code="2">doi</subfield> </datafield> </record>
