Topological characterization of dynamic chiral magnetic textures using machine learning
Tim Matthies, Alexander F. Schäffer, Thore Posske +2
Recently proposed spintronic devices use magnetic skyrmions as bits of information. The reliable detection of those chiral magnetic objects is an indispensable requirement. Yet, th…
Creating arbitrary sequences of mobile magnetic skyrmions and antiskyrmions
Pia Siegl, Martin Stier, Alexander F. Schäffer +4
Magnetic skyrmions and their anti-particles, the antiskyrmions, are stable magnetic solitons existing down to the nanometer scale. Their stability and size as well as the possibili…
Rotating edge-field driven processing of chiral spin textures in racetrack devices
Alexander F. Schäffer, Pia Siegl, Martin Stier +5
Topologically distinct magnetic structures like skyrmions, domain walls, and the uniformly magnetized state have multiple applications in logic devices, sensors, and as bits of inf…
Size-dependent frequency bands in the ferromagnetic resonance of a Fe-nanocube
Alexander F. Schäffer, Alexander Sukhov, Jamal Berakdar
Using full micromagnetic simulations we calculate the spectra of ferromagnetic resonance (FMR) for an iron (core-shell) nanocube and show that the FMR characteristics are strongly…
Optical vortex driven charge current loop and optomagnetism in fullerenes
Jonas Wätzel, Yaroslav Pavlyukh, Alexander Schäffer +1
Endohedral molecular magnets, e.g. as realized in fullerenes containing , are promising candidates for molecular electronics and quantum information processing. For…
