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…
Emergence of multiple topological spin textures in an all-magnetic van der Waals heterostructure
Moritz A. Goerzen, Tim Drevelow, Hendrik Schrautzer +3
Magnetic solitons such as skyrmions and bimerons show great promise for both fundamental research and spintronic applications. Stabilizing and controlling topological spin textures…
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…
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…
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…
Bilayer triple-Q state driven by interlayer higher-order exchange interactions
Bjarne Beyer, Mara Gutzeit, Tim Drevelow +3
Using first-principles calculations and an atomistic spin model we predict the stabilization of a bilayer triple-Q state in an atomic Mn bilayer on Ir(111) due to interlayer higher…
