Skyrmions in 2D chiral magnets with noncollinear ground states stabilized by higher-order interactions
Mathews Benny, Moinak Ghosh, Moritz A. Goerzen +4
Magnetic skyrmions are intriguing topological spin textures that have attracted great attention due to their potential for future spintronic devices. Skyrmions have so far been exp…
Network of localized magnetic textures revealed using a saddle-point search framework
Hendrik Schrautzer, Tim Drevelow, Hannes Jónsson +1
A computational framework is presented for the sampling of the energy surface of magnetic systems via the systematic identification of first-order saddle points that determine conn…
Impact of higher-order exchange on the lifetime of skyrmions and antiskyrmions
Hendrik Schrautzer, Moritz A. Goerzen, Bjarne Beyer +3
Reliable control of skyrmion lifetime is essential for realizing spintronic devices, yet the role of higher-order exchange - which can lead to skyrmion stabilization - remains larg…
Entropy-driven phase transition in a non-collinear antiferromagnet due to higher-order exchange interactions
Leo Kollwitz, Moritz A. Goerzen, Bjarne Beyer +2
The triple-Q state arises due to the superposition of three symmetry equivalent spin spirals stabilized by higher-order exchange interactions. It has been predicted more than 20 ye…
Eigenmode following for direct entropy calculation and characterization of magnetic systems
Stephan von Malottki, Moritz A. Goerzen, Hendrik Schrautzer +2
We present an eigenmode following method (EMF) that has been developed for the numerical scanning of the potential energy surface and the direct calculation of entropy and pre-expo…
