Entropy-limited topological protection of skyrmions
J. Wild, T. N. G. Meier, S. Pöllath +11
Magnetic skyrmions are topologically protected whirls that decay through singular magnetic configurations known as Bloch points. We have used Lorentz transmission electron microsco…
Topological domain walls in helimagnets
P. Schoenherr, J. Müller, L. Köhler +5
A magnetic helix arises in chiral magnets with a wavelength set by the spin-orbit coupling. We show that the helimagnetic order is a nanoscale analog to liquid crystals, exhibiting…
Shape-dependence of the barrier for skyrmions on a two-lane racetrack
Jan Müller
Single magnetic skyrmions are localized whirls in the magnetization with an integer winding number. They have been observed on nano-meter scales up to room temperature in multilaye…
Magnetic skyrmions and skyrmion clusters in the helical phase of CuOSeO
Jan Müller, Jayaraman Rajeswari, Ping Huang +4
Skyrmions are nanometric spin whirls that can be stabilized in magnets lacking inversion symmetry. The properties of isolated skyrmions embedded in a ferromagnetic background have…
Motion of skyrmions in nanowires driven by magnonic momentum-transfer forces
Xichao Zhang, Jan Müller, Jing Xia +3
We study the motion of magnetic skyrmions in a nanowire induced by a spin-wave current flowing out of a driving layer close to the edge of the wire. By applying micromagnetic s…
Edge instabilities and skyrmion creation in magnetic layers
Jan Müller, Achim Rosch, Markus Garst
We study both analytically and numerically the edge of two-dimensional ferromagnets with Dzyaloshinskii-Moriya (DM) interactions, considering both chiral magnets and magnets with i…
