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…
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…
Strongly enhanced lifetime of higher-order bimerons and antibimerons
Shiwei Zhu, Moritz A. Goerzen, Changsheng Song +2
Magnetic bimerons, similar to skyrmions, are topologically nontrivial spin textures characterized by topological charge . Most studies so far have focused on low- solitons ($…
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…
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…
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…
Strain-driven domain wall network with chiral junctions in an antiferromagnet
Vishesh Saxena, Mara Gutzeit, Arturo Rodríguez-Sota +6
Materials with antiferromagnetic order have recently emerged as promising candidates in spintronics based on their beneficial characteristics such as vanishing stray fields and ult…
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…
Prediction of stable nanoscale skyrmions in monolayer FeGeTe
