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…
Strongly enhanced lifetime of higher-order bimerons and antibimerons
Shiwei Zhu, Moritz A. Goerzen, Changsheng Song +2
Magnetic bimerons, similar to skyrmions, are topologically nontrivial spin textures characterized by topological charge . Most studies so far have focused on low- solitons ($…
A new skyrmion topological transition driven by higher-order exchange interactions in Janus MnSeTe
Megha Arya, Moritz A. Goerzen, Lionel Calmels +4
Two-dimensional (2D) van der Waals magnets offer a promising platform for pushing skyrmion technology to the single-layer limit with high tunability. While Dzyaloshinskii-Moriya in…
Lifetime of bimerons and antibimerons in two-dimensional magnets
Moritz A. Goerzen, Tim Drevelow, Soumyajyoti Haldar +3
Soliton-based computing architectures have recently emerged as a promising avenue to overcome fundamental limitations of conventional information technologies, the von Neumann bott…
Long lifetimes of nanoscale skyrmions in lithium-decorated van der Waals ferromagnet FeGeTe
Soumyajyoti Haldar, Moritz A. Goerzen, Stefan Heinze +1
The Dzyaloshinskii-Moriya interaction (DMI), which originates from spin-orbit coupling and relies on broken inversion symmetry, is recognized as a key ingredient in forming magneti…
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…
