Topological and spin-orbit effects on orbital moments in ultra-thin magnetic films
Felix Nickel, Soumyajyoti Haldar, Mara Gutzeit +1
Topological orbital moments (TOMs) are a direct hallmark of a magnetic texture with a non-trivial spin topology. In addition to giving insight into the topology of the magnetic tex…
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…
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…
First-principles investigation of magnetic exchange force microscopy on adatoms adsorbed on an antiferromagnetic surface
Soumyajyoti Haldar, Stefan Heinze
Using density functional theory (DFT), we calculate the magnetic short-ranged exchange forces between a magnetic tip and an adatom adsorbed on the antiferromagnetic Mn monolayer on…
Kicking Co and Rh atoms on a row-wise antiferromagnet
Felix Zahner, Soumyajyoti Haldar, Roland Wiesendanger +3
Diffusion on surfaces is a fundamental process in surface science, governing nanostructure and film growth, molecular self-assembly, and chemical reactions. Atom motion on non-magn…
