Skyrmion Lattice Domain Formation in a Non-Flat Energy Landscape
Raphael Gruber, Jan Rothörl, Simon M. Fröhlich +9
Magnetic skyrmions are chiral spin structures with non-trivial topology that comprise two-dimensional quasi-particles and are promising information carriers for data storage and pr…
Skyrmion Lattice Order Controlled by Confinement Geometry
Raphael Gruber, Jan Rothörl, Simon M. Fröhlich +8
Magnetic skyrmions forming two-dimensional (2D) lattices provide a versatile platform for investigating phase transitions predicted by Kosterlitz-Thouless-Halperin-Nelson-Young (KT…
Real-Time Modeling of Skyrmion Dynamics in Arbitrary 2D Spatially Dependent Pinning Potential Landscapes
Simon M. Fröhlich, Tobias Sparmann, Maarten A. Brems +6
Non-flat energy landscapes leading to localized pinning of skyrmions pose an inherent and unavoidable challenge for studies of fundamental 2D spin structure dynamics as well as app…
Realizing Quantitative Quasiparticle Modeling of Skyrmion Dynamics in Arbitrary Potentials
Maarten A. Brems, Tobias Sparmann, Simon M. Fröhlich +7
We demonstrate fully quantitative Thiele model simulations of magnetic skyrmion dynamics on previously unattainable experimentally relevant large length and time scales by ascertai…
Imaging Topological Defect Dynamics Mediating 2D Skyrmion Lattice Melting
Raphael Gruber, Jan Rothörl, Simon M. Fröhlich +8
Topological defects are the key feature mediating 2D phase transitions. However, both resolution and tunability have been lacking to access the dynamics of the transitions. With dy…
