Popis: |
We report on a reciprocal magnetic interaction mechanism in micrometer-sized hybrid Co/Pd-Permalloy square elements. Time-resolved scanning transmission X-ray microscopy using X-ray magnetic circular dichroism contrast together with micromagnetic simulations demonstrate that there exists a mutual imprint of vortices in the Permalloy and in the stripe domains of the Co/Pd. This results in a hybrid magnetic domain structure leading to a domain confined gyroscopic vortex precession. These observations open the exciting possibility for topological control of vortex core motion. |
