Thermal stability and topological protection of skyrmions in nanotracks
David Cortés-Ortuño, Weiwei Wang, Marijan Beg +7
Magnetic skyrmions are hailed as a potential technology for data storage and other data processing devices. However, their stability against thermal fluctuations is an open questio…
Magnonic analog of relativistic Zitterbewegung in an antiferromagnetic spin chain
Weiwei Wang, Chenjie Gu, Yan Zhou +1
We theoretically investigate the spin wave (magnon) excitations in a classical antiferromagnetic spin chain with easy-axis anisotropy. We obtain a Dirac-like equation by linearizin…
Current-induced instability of domain walls in cylindrical nanowires
Weiwei Wang, Zhaoyang Zhang, Ryan A. Pepper +3
We study the current-driven domain wall (DW) motion in cylindrical nanowires using micromagnetic simulations by implementing the Landau-Lifshitz-Gilbert equation with nonlocal spin…
Hysteresis of nanocylinders with Dzyaloshinskii-Moriya interaction
Rebecca Carey, Marijan Beg, Maximilian Albert +6
The potential for application of magnetic skyrmions in high density storage devices provides a strong drive to investigate and exploit their stability and manipulability. Through a…
Dynamics of skyrmionic states in confined helimagnetic nanostructures
Marijan Beg, Maximilian Albert, Marc-Antonio Bisotti +9
In confined helimagnetic nanostructures, skyrmionic states in the form of incomplete and isolated skyrmion states can emerge as the ground state in absence of both external magneti…
Proposal of a micromagnetic standard problem for ferromagnetic resonance simulations
Alexander Baker, Marijan Beg, Gregory Ashton +10
Nowadays, micromagnetic simulations are a common tool for studying a wide range of different magnetic phenomena, including the ferromagnetic resonance. A technique for evaluating r…
