Синхронизация Автоколебаний Обменно-Связанных Магнитных Вихрей

Abstract

The results of micromagnetic modeling of the gyrotropic mode of magnetization auto-oscillations in overlapping ferromagnetic disks under the action of a spin-polarized current are presented. It is shown that the exchange interaction between disks significantly increases the binding energy of magnetic vortices and, as a consequence, reduces the dephasing of the vortex core gyration in neighboring disks.
