Topological spin textures in an antiferromagnetic monolayer
Felix Zahner, Tim Drevelow, Roberto Lo Conte +3
Topological spin structures such as magnetic skyrmions are of fundamental interest and promising for various types of applications in spintronics. Skyrmions have been predicted to…
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…
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…
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…
Evidence for a conical spin spiral state in the Mn triple-layer on W(001): spin-polarized scanning tunneling microscopy and first-principles calculations
Paula M. Weber, Tim Drevelow, Jing Qi +2
The spin structure of a Mn triple layer grown pseudomorphically on surfaces is studied using spin-polarized scanning tunneling microscopy (SP-STM) and density functional theory (DF…
