Robust formation of nanoscale magnetic skyrmions in easy-plane thin film multilayers with low damping
Luis Flacke, Valentin Ahrens, Simon Mendisch +14
We experimentally demonstrate the formation of room-temperature skyrmions with radii of about 25\,nm in easy-plane anisotropy multilayers with interfacial Dzyaloshinskii-Moriya int…

Controlling Domain-Wall Nucleation in Ta/CoFeB/MgO Nanomagnets via Local Ga+ Ion Irradiation
Simon Mendisch, Fabrizio Riente, Valentin Ahrens +6
Comprehensive control of the domain wall nucleation process is crucial for spin-based emerging technologies ranging from random-access and storage-class memories over domain-wall l…
