Deutsche Forschungsgemeinschaft (DFG) - Project number 259181367
The project is a result of a long-term bi- and tri-lateral cooperation of Münster University, TU Kaiserslautern, and St. Petersburg Electrotechnical University, Russia. The main aim of the cooperation is study of various fundamental nonlinear spin-wave phenomena. Here we main-ly focus ourselves on generation of spin-wave single- and multi-solitonic wavepackets with controllable shape, synchronization of spin-wave chaotic oscillations in active rings based on ferromagnetic films and multiferroic layered structures, as well as nonlinear spin-wave modes in metallic magnetic micro- and nanosystems with low damping confined in the two lateral dimensions driven by spin currents, A simultaneous study of both active and passive magnetic systems allows us a comprehensive investigation of a wide variety of effects that belong to the most modern directions of magnetism. The experiments will be carried out us-ing several complementary techniques, namely, traditional and traveling-wave microwave spectroscopy, as well as time-, space-, and phase-resolved Brillouin light scattering spec-troscopy, including the unique near-field BLS spectrometer, allowing for two-dimensional spatial visualization and characterization of spin-wave propagation. The expected results will not only allow us to obtain fundamental information on specific nonlinear spin-wave process-es but will contribute to a deeper understanding of the field of nonlinear wave physics in general, as well as to consider possible applications of the investigated nonlinear processes for spintronics and magnonics.
