Sub-20 nm spin textures with arbitrary topological charge stabilized by higher-order interactions
Zhen Sun, Shiwei Zhu, Moritz A. Goerzen +3
Topological magnetization textures play a central role in modern magnetism. For many applications, spin textures with different topological charges in the same system are parti…
Finite-temperature phase transitions across spin symmetries in two-dimensional magnets

Recent advances in intrinsic two-dimensional (2D) magnets have created a need for a unified understanding of finite-temperature phase transitions across different spin-symmetry cla…
Beating micromagnetic limits on skyrmion stability by long-range frustration
Shiwei Zhu, Moritz A. Goerzen, Changsheng Song +1
Skyrmion stability is commonly assumed to scale with skyrmion size or exchange stiffness within micromagnetic models. Here, we demonstrate that long-range exchange frustration can…
Extended saddle points govern long-lived antiskyrmions
Megha Arya, Moritz A. Goerzen, Lionel Calmels +4
Achieving long-lived nanoscale magnetic solitons remains a central challenge, as their lifetimes typically decrease rapidly with temperature. Here, we demonstrate that anisotropic…
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…
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…
