Interaction of Domain Walls and Skyrmions — •Venkata Krishna Bharadwaj, Kyoung-Whan Kim, and Karin Everschor Sitte — Johannes Gutenberg Universität

Magnetic domain walls and skyrmions are promising candidates for spintronics applications such as racetrack memory devices. Motivated by recent experiments [1-3], we study the interactions between domain walls and skyrmions and their interplay in the presence of inhomogeneous current distributions. In the first step, we perform numerical simulations with Micromagnum [4] with some software extensions to analyze the production of different magnetic textures and the possibility to form skyrmions upon the collision of domain walls.
