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…
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…
Antiferromagnetic order of topological orbital moments in atomic-scale skyrmion lattices
Felix Nickel, André Kubetzka, Mara Gutzeit +3
Topological orbital moments can arise in non-coplanar spin structures even in the absence of spin-orbit coupling and a net topological orbital magnetization occurs for the triple-Q…
Spontaneous square vs. hexagonal nanoscale skyrmion lattices in Fe/Ir(111)
Mara Gutzeit, Tim Drevelow, Moritz A. Goerzen +2
We study the emergence of spontaneous skyrmion lattices in an Fe monolayer in fcc and hcp stacking on the Ir(111) surface using density functional theory (DFT). For fcc-Fe/Ir(111)…
Nano-scale collinear multi-Q states driven by higher-order interactions
Mara Gutzeit, André Kubetzka, Soumyajyoti Haldar +4
Complex magnetic order arises due to the competition of different interactions between the magnetic moments. Recently, there has been an increased interest in such states not only…
Trends of higher-order exchange interactions in transition-metal trilayers
Mara Gutzeit, Soumyajyoti Haldar, Sebastian Meyer +1
We present a systematic study of higher-order exchange interactions beyond the pair-wise Heisenberg exchange in transition-metal trilayers based on density functional theory calcul…
Electronic and magnetic properties of 3 transition-metal adatoms on Mn/W(110)
Mara Gutzeit, Soumyajyoti Haldar, Stefan Heinze
Using density functional theory, we investigate the electronic and magnetic properties of transition-metal adatoms adsorbed on a monolayer of Mn on W(110). Mn/W(110) has a non…
Quantifying Exchange Forces of a Non-Collinear Magnetic Structure on the Atomic Scale
Nadine Hauptmann, Soumyajyoti Haldar, Tzu-Chao Hung +5
The large interest in chiral magnetic structures for realization of nanoscale magnetic storage or logic devices has necessitated methods which can quantify magnetic interactions at…
Tunneling anisotropic magnetoresistance of Pb and Bi adatoms and dimers on Mn/W(110): A first-principles study
Soumyajyoti Haldar, Mara Gutzeit, Stefan Heinze
We show that Pb and Bi adatoms and dimers have a large tunneling anisotropic magnetoresistance (TAMR) of up to 60% when adsorbed on a magnetic transition-metal surface due to stron…
