Simulating Magnetization Dynamics of Ferromagnetic Vortices

Poster Paper

Using the “Object Oriented Micro-Magnetic Framework” (OOMMF), we will show that ferromagnetic vortices naturally create localized magnetic fields capable of inducing “Electron Spin Resonance” (ESR). To determine how to control the vortices’ magnetic fields, we will study their magnetization dynamics in response to static and time-varying external fields. Using this information, we hope to control electron spins in neighboring semiconductor structures. Future technologies will be able to use this data to create ferromagnetic vortexes to induce ESR and thus control and communicate between electrons.
