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…
Controlled Creation of Quantum Skyrmions
Pia Siegl, Elena Y. Vedmedenko, Martin Stier +2
We study the creation of quantum skyrmions in quadratic nanoscopic lattices of quantum spins coupled by Dzyaloshinkii-Moriya and exchange interactions. We numerically show that dif…
Role of impurity clusters for the current-driven motion of magnetic Skyrmions
M. Stier, R. Strobel, W. Häusler +1
We study how impurities influence the current-induced dynamics of magnetic Skyrmions moving in a racetrack geometry. For this, we solve numerically the generalized Landau-Lifshitz-…
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…
Steering of the Skyrmion Hall Angle By Gate Voltage
J. Plettenberg, M. Stier, M. Thorwart
Magnetic skyrmions can be driven by an applied spin-polarized electron current which exerts a spin-transfer torque on the localized spins constituting the skyrmion. However, the lo…
Dragging of magnetic domain walls by interlayer exchange
Martin Stier, Jennifer Erdmann, Michael Thorwart
Magnetic domain walls can be moved by spin-polarized currents due to spin-transfer torques. This opens the possibility to use them in spintronic memory devices as, e.g., in racetra…
