Abstract: Spin transfer torque allows excitation of magnetization dynamics in ferromagnetic thin films. An electric current owing through a nanocontact to a ferromagnetic thin film can create spin waves, which are governed by the Landau-Lifschitz-Gilbert-Slonczewski equation. In this project we study the behavior of localized spin-wave modes, which are called magnetic droplet solitons. The system is analyzed with micromagnetic numerical simulations of an array of spins. We study the stability of magnetic droplet solitons. We analyzed the conditions for creation and annihilation and the effect of external applied fields.
