Symmetry- and curvature effects on spin waves in vortex-state hexagonal nanotubes
Lukas Körber, Michael Zimmermann, Sebastian Wintz +13
Analytic and numerical studies on curved magnetic nano-objects predict numerous exciting effects that can be referred to as magneto-chiral effects, which do not originate from intr…
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…
Experimental observation of the curvature-induced asymmetric spin-wave dispersion in hexagonal nanotubes
Lukas Körber, Michael Zimmermann, Sebastian Wintz +9
Theoretical and numerical studies on curved magnetic nano-objects predict numerous exciting effects that can be referred to as magneto-chiral effects, which do not originate from t…
The effect of curvature on the eigenexcitations of magnetic skyrmions
Anastasiia Korniienko, Attila Kákay, Denis D. Sheka +1
Spectrum of spin eigenmodes localized on a ferromagnetic skyrmion pinned by a geometrical defect (bump) of magnetic films is studied theoretically. By means of direct numerical sol…
Micromagnetic Theory of Curvilinear Ferromagnetic Shells
Denis D. Sheka, Oleksandr V. Pylypovskyi, Pedro Landeros +3
Here, we present a micromagnetic theory of curvilinear ferromagnets, which allows discovering novel fundamental physical effects which were amiss. In spite of the firm confidence f…
Multiscale and multimodel simulation of Bloch point dynamics
Christian Andreas, Attila Kákay, Riccardo Hertel
We present simulation results on the structure and dynamics of micromagnetic point singularities with atomistic resolution. This is achieved by embedding an atomistic computational…
Quenched Slonczewski-Windmill in Spin-Torque Vortex-Oscillators
Volker Sluka, Attila Kákay, Alina M. Deac +3
We present a combined analytical and numerical study on double-vortex spin-torque nano-oscillators and describe a mechanism that suppresses the windmill modes. The magnetization dy…
The magnonic limit of domain wall propagation in ferromagnetic nanotubes
Ming Yan, Christian Andreas, Attila Kákay +2
We report a study on the field-driven propagation of vortex-like domain walls in ferromagnetic nanotubes. This particular geometry gives rise to a special feature of the static wal…
Fast, Preisach-like characterization of hysteretic systems
Marek W. Gutowski, Lajos K. Varga, Attila Kákay
Proposed is a substantially simplified, Preisach-like model for characterization of hysteretic systems, in particular magnetic systems. The main idea is to replace a two-dimensiona…
