Voltage controlled magnetization dynamics in nanostructured multiferroic multilayer systems — •Alexander F. Schäffer and Jamal Berakdar — Institute of Physics, Martin-Luther-Universität Halle-Wittenberg, 06099 Halle (Saale), Germany

We investigate the control of magnetization dynamics by applying localized voltages in the framework of nanostructured multiferroic heterostructures. Manipulations of the magnetic anisotropy are spatially controlled by nanostructuring. This combination is utilized as a toolbox to excite or manipulate magnetic systems in order to manipulate multiple magnetic phenomena, such as the magnon dispersion, local spin current sources, or local non-collinear magnetic textures. Full-fledged numerical calculations for realistic systems along with basic analytical models will be shown in order to point towards opportunities for further experimental investigations and applications.
