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…

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…
