Baryakhtar Institute of Magnetism of the National Academy of Sciences of Ukraine (IMag NAS of Ukraine) popup.description1 Theoretical and experimental study of nonlinear interaction of propagating spin waves with different types of localized pumping and stochastic spin-wave dynamics in magnetic nanostructures and systems based on them, and development of the operational principles of elements of non-Boolean (probabilistic and neuromorphic) magnonic computing systems on the basis of the studied physics laws. popup.description2 New and improved magnonics devices have been proposed and demonstrated: a unidirectional spin-wave emitter with the ability of rapid (within nanoseconds) change of emission direction; a universal nonlinear spin-wave coupler based on the discovered effect of nonlinear suppression of the coupling between magnonic waveguides; and a multifunctional spin-wave coupler based on magnonic waveguides with perpendicular static magnetization, which exhibits unique nonreciprocal properties and the ability of smooth tuning of characteristics by a domain wall motion. It has been established that Bloch lines in ferrimagnetic domain walls near the point of compensation of spin densities of sublattices can move much faster than in conventional ferromagnets, which is interesting for the development of high-speed magnonics and spintronics devices.
