popup.description1
A detailed study of ways for controlling nonlinear three- and four-magnon processes in single- and multi-layer magnetic nanostructures, as well as the development of methods of utilization of the revealed features for the extension of spintronics nanoelements functionality.
popup.description2
The possibility of efficient control of the intensity and selection rules of three-magnon scattering processes by controlled perturbation of the magnetic state symmetry is demonstrated. For nanodots in a saturated state, the effect of perturbations of all possible symmetries on the three-magnon processes is systematized, and the relation between perturbation symmetry and symmetry of the modes involved in a three-magnon process affected by the perturbation is esteblished. It was found that mode hybridization in multilayer nanostructures can be an efficient mechanism for controlling four-magnon processes and, accordingly, the second-order parametric instability.
